Social Media Algorithms and Design Spread Antisemitism — Not Foreign Actors

Recently, as Jewish Insider reported, bipartisan lawmakers in Congress hailed what they saw as a major advance in fighting online antisemitism — X’s new location feature.
The new tool, showing which country an account operates from — had started revealing that some accounts spreading antisemitic content in US political discussions were based overseas. For legislators on both sides, this represented a digital unmasking.
Rep. Don Bacon (R-NE) remarked that the feature exposed “foreign interests trying to spread antisemitic poison” while “masquerading as Americans.”
Sen. James Lankford (R-OK) insisted Americans “deserve to know which accounts are run from abroad, so we know the true source of these narratives.” Rep. Tom Suozzi (D-NY) took a geopolitical view: “Beijing, Moscow and Tehran know they cannot defeat us economically or militarily, so they exploit controversial issues, like Israel and antisemitism, and try to divide.” Former UN Ambassador Nikki Haley declared the feature “a huge win for transparency and American security.”
The story is appealing: foreign enemies weaponize antisemitism to fracture American unity, and transparency about account origins helps us counter these external threats. There’s truth here — bad actors do exploit divisive topics.
But this celebration reveals a dangerous misdiagnosis.
As the lead of the Decoding Antisemitism project — which has examined over 300,000 items of digital content across multiple crises — I’ve identified three distinct but connected drivers of online antisemitic radicalization: coordinated malicious actors (foreign and domestic), algorithmic amplification through platform design, and homegrown participatory dynamics enabled by online communication itself — anonymity, mutual reinforcement, and the normalization of extremism through constant exposure.
The issue isn’t that foreign influence exists — it does. The problem is treating it as the primary driver while overlooking the structural and domestic conditions that allow antisemitic narratives to take root and spread.
How we diagnose problems determines how we design solutions — and misdiagnosis doesn’t just limit our response, it actively redirects resources, attention, and political will away from factors we can actually control.
Comprehending online antisemitism demands a virological approach: examining not just where accounts originate, but how hate narratives evolve, which platform features enable transmission, and what conditions allow them to thrive. Yet social media platforms remain essentially black boxes — we lack systematic tools to understand dynamics unfolding within these digital spaces.
Lawmakers celebrate a feature revealing account geography while leaving the actual black box — algorithmic recommendations, engagement optimization, and content amplification — completely unexamined.
The Conflation Problem
The Jewish Insider article and quoted lawmakers collapse “foreign,” “adversarial,” and “antisemitic” into one category. This conflation obscures more than it reveals.
It treats geographic origin as definitive of intent and impact. An account in South Asia or Eastern Europe engaging with US politics isn’t necessarily a state-directed operation. It may simply be someone with opinions about American affairs. Account location reveals nothing about whether content is coordinated, conspiratorial, state-driven, or simply individual opinion.
More crucially, emphasizing foreign accounts distracts from what we know empirically about domestic antisemitic content production.
Following the October 7 attacks, antisemitic discourse surged to 36-38% of comments on major UK news outlet YouTube channels — nearly double the pre-crisis baseline. After the Washington museum shooting in May 2025, antisemitic content averaged 43% across major English-language news channels, with some reaching 66%.
These aren’t fringe platforms infiltrated by foreign bots — they’re mainstream digital spaces where domestic audiences actively produce and amplify antisemitic narratives.
Research on antisemitic discourse spread reveals a three-phase domestic process: elite figures make strategically ambiguous statements, digital intermediaries (podcasters, YouTubers, influencers) reframe and sharpen this messaging, and comment sections collapse ambiguity into explicit hate speech.
This “cascading radicalization” is primarily homegrown, driven by domestic actors and platform dynamics — not solely foreign infiltration.
Our analysis cannot definitively establish every anonymous commenter’s geographic origin. What we observe are linguistic and cultural markers — idiom, references, political framings — indicating domestic participation, combined with the absence of coordination patterns typical of bot networks. The antisemitic discourse we documented emerges through “dialogical warfare”: organic exchanges between users presenting as ordinary Americans who deploy antisemitism as an explanatory framework for complex issues.
When a US Congressmember amplifies antisemitic tropes, when popular podcasts platform guests trafficking in conspiracy theories about Jewish power, when partisan media deploy dual loyalty accusations — these aren’t foreign operations. They’re homegrown productions embedded in American political discourse and amplified through domestic networks.
The Missing Architecture
Most striking about celebrating X’s location feature is what remains unexamined: the platform itself.
There’s virtually no discussion about platform design, algorithmic amplification, recommendation systems, the attention economy, or structural dynamics allowing hateful content to scale. The feature is treated as inherently truth-revealing, exposing hidden foreign manipulation.
But this framing evades more important questions: why do certain narratives spread, how do platform architectures enable amplification, and how do online communication conditions — anonymity, mutual reinforcement, constant exposure to extremity — create environments where antisemitic ideas mutate and take hold?
The answer has little to do with account location and everything to do with how platforms are built. Engagement-based algorithms reward emotionally provocative content — outrage, fear, tribal solidarity. Recommendation systems create filter bubbles and radicalization pathways. Virality architecture privileges simplification, moral clarity, and villain identification. The attention economy systematically rewards polarizing, enraging content. These are design choices, not inevitable features.
Meanwhile, online communication conditions themselves — anonymity removing social accountability, mutual confirmation among like-minded voices, omnipresent hate speech normalizing extremity — create participatory environments where ordinary users become active radicalization contributors.
Contemporary antisemitism increasingly operates through coded expressions, memes, and multimodal signals evading simple keyword detection. The watermelon emoji, the paraglider symbol — these function as in-group markers regardless of geographic location. Strategic ambiguity, not foreign origin, enables antisemitic narratives to spread while maintaining plausible deniability.
The Political Convenience
The “foreign adversaries spreading antisemitism” narrative aligns with a bipartisan preference: attributing social breakdown to hostile external actors. This framing is politically convenient across the spectrum.
For Republicans, it allows condemning antisemitism without confronting how right-wing media has mainstreamed antisemitic conspiracy theories — “great replacement” narratives, George Soros accusations, “globalist” rhetoric. For Democrats, it enables criticizing online hate without reckoning with how segments of progressive activism have normalized anti-Zionist rhetoric often sliding into antisemitic tropes about Jewish power and loyalty.
The foreign influence frame permits symbolic accountability –the appearance of action without institutional change. Lawmakers can call for location transparency, celebrate platform implementations, and position themselves as defenders against external threats. What they needn’t do is examine how American political rhetoric contributes to normalizing antisemitism, push for regulatory interventions altering platform incentives, or confront how online communication creates radicalization pathways.
This isn’t analytical sloppiness. It’s moral abdication.
What Accountability Would Actually Require
Genuine accountability for online antisemitism requires confronting all three drivers — not just one.
First, acknowledging that while malicious actors (foreign and domestic) exploit divisive issues, they operate within a larger ecosystem. We must recognize the United States as an active site where antisemitic ideas are produced, circulated, and normalized through domestic political culture, media ecosystems, and participatory online dynamics — not merely as an innocent target.
Second, confronting how platform architecture shapes what spreads, and demanding transparency not just about account locations but about algorithmic recommendations, content moderation, the attention economy’s incentives, and metrics driving platform design.
Third, recognizing that high-profile domestic actors — politicians, media figures, influencers with millions of followers — bear far more responsibility for mainstreaming antisemitic narratives than anonymous accounts. We must understand the three-phase process through which elite ambiguity cascades into radicalized discourse.
Fourth, examining how partisan political discourse traffics in antisemitic tropes through strategic ambiguity — and being willing to call this out when politically inconvenient.
Fifth, acknowledging online communication conditions themselves — anonymity, mutual reinforcement, constant exposure to extremity — are creating environments where ordinary users become radicalization participants.
X’s location feature may provide useful information about one factor among many. But treating this as revelatory, exposing the “true source” of antisemitic narratives, is a dangerous misdiagnosis.
If democracies want to confront antisemitism seriously, they must address all three drivers: monitor and counter malicious actors where they exist, examine platform architectures amplifying hate, and confront participatory dynamics and communication conditions enabling antisemitic narratives to flourish in mainstream spaces.
How we diagnose problems shapes how we conceptualize solutions. Focusing exclusively on foreign actors may be politically convenient. It will not protect the public sphere.

Israel gives in to the politics of debasement
A small episode this week crystallized the broader pathology of Israeli Prime Minister Benjamin Netayahu more clearly than any grand speech or ideological argument ever could: the Knesset vote for state comptroller, one of the most sensitive institutional positions in Israeli public life.
In Israel, the 120 members of the Knesset elect the comptroller by secret ballot. The office audits government ministries, investigates failures of governance, oversees public integrity, and possesses enormous influence over public accountability. In the aftermath of the Hamas attack of Oct. 7, 2023, and the Gaza war, the role carries even greater significance. The comptroller may shape future investigations into catastrophic national failures and wartime decision-making.
This week — in a move straight out of United States President Donald Trump’s playbook — Netanyahu nominated his longtime personal lawyer, Michael Rabello, for the role.
Historically, the comptroller’s office has been occupied by senior judges, jurists, or respected public servants with reputations for independence. Figures such as Miriam Ben-Porat, Eliezer Goldberg, and Micha Lindenstrauss embodied a certain ethos: they were stern institutional guardians standing somewhat above partisan warfare.
The idea of placing the prime minister’s own attorney into the country’s central oversight institution struck many Israelis as grotesquely inappropriate.
Yet the truly astonishing part came during the voting itself, in which the opposition candidate was a former justice on the Supreme Court — an institution Netanyahu’s coalition has long vilified. The first round reportedly revealed substantial defections among Netanyahu’s coalition. His preferred candidate fell short. Panic spread.
Suddenly, allegations and reports emerged that coalition lawmakers were being encouraged to photograph or film their ballots in order to prove their loyalty. There was a pause in the proceedings as the Knesset speaker, Likud’s Amir Ohana, received legal advice to not allow phones in the voting area. He restarted the vote anyway. Israeli media filled with coalition lawmakers posting images of themselves voting the right way. The images and reports were the excruciating stuff of banana republics.
I cannot recall ever seeing a similar scene in a functioning democracy. Rabello was elected.
Secret ballots exist precisely because democracies understand that free voting collapses when superiors can verify obedience. The entire purpose of ballot secrecy is to protect individuals from coercion, intimidation, retaliation and patronage systems.
Modern democracies adopted secret ballots in the nineteenth century to break the power of bosses, landlords, oligarchs, and political machines that demanded proof of loyalty.
The blatant violation of these norms by Netanyahu’s coalition helps explain why so many Israelis react to him not merely with opposition, but with exhaustion, fury, and moral revulsion.
It’s not just the corruption trials, the permanent manipulation, the serial falsehoods, the failed strategic assumptions about Hamas, the relentless cultivation of tribal resentment, the attacks on state institutions, the politics of personal loyalty and the transformation of every disagreement into an existential struggle between patriots and traitors. It’s the cumulative exhaustion of watching every institutional norm eventually be subordinated to the most vulgar politics imaginable.
The episode revealed something larger than one parliamentary scandal: the culture Netanyahu has spent years cultivating. It is a system organized increasingly around personal allegiance rather than institutional responsibility. A political environment in which independent judgment becomes suspicious, dissent becomes betrayal, and every institution gradually bends toward one man’s political ambition.
So we have here a prime minister under criminal indictment pushing his own lawyer into a top civil service oversight role.
Opposition leaders Naftali Bennett and Yair Lapid plan to appeal Rabello’s election to the Supreme Court, calling the vote “tainted.” Even that might not work. Several government ministers, including the justice minister, have suggested in recent months that they no longer consider court decisions binding.
And that is what outsiders often miss about Netanyahu fatigue in Israel. The anger does not emerge from one scandal, one trial, one war, or one speech. It comes from the constant sense of humiliation. This week, inside Knesset voting booths that were meant to be hidden from view, Israelis saw the whole story compressed into a single degrading scene.

My irrational, possibly problematic obsession with an $85 yarmulke
Growing up, we had a rule of thumb about yarmulkes: the closer yours was to your forehead, the more strictly religious you were. The frum bochurim placed theirs practically on their noses; the boys from Conservative families bobby-pinned their kippahs on the back of their heads, like climbers gripping a rockface. The cool kids, of course, stuffed theirs in their pockets.
The Jewish skullcap, in other words, was a signifier of much more than the religious precept it embodied. Over the years not only a yarmulke’s positioning but also its style, size and material have come to place its wearer somewhere on a continuum of Jewish identity. Trends in yarmulke wearing, then, may tell us a story about where Judaism is — forgive me — headed.
So what kind of Jew wears an $85 yarmulke, and what kind of Judaism demands it? These questions gnawed at me when I first learned about Rubenstein Paris, a new kippah couturier whose ads found me on Instagram. Available in a range of expensive-looking solid colors (copper, cream, sapphire) and fabrics (velvet, corduroy, even horsehair), these kippahs are here to replace your tattered souvenirs.
“Everybody’s just walking around with their kippot from — I don’t know, Mendel and Rachel’s wedding, 2019,” Jonathan Hirsch, Rubenstein’s German-Israeli founder, told me recently. “I was like, ‘It’s such a sacred item, you know? Why isn’t there any beautiful kippah, that you can really acknowledge for what it is?’”

He’s onto something. Even as an image-conscious, Shabbat-observant millennial, I had largely neglected the yarmulke; when I wanted to look sharp, I ditched it. I was not completely out on Jew-caps, to be sure — like every other frat boy who thought Mac Miller was Moses, I went through a vintage snapback phase in college. But when I’ve had to clip up, I’ve made do with whatever I had lying around — usually something suede, dark, and folded more times than an origami fortune teller.
Hirsch offered to send a freebie, but at $85, accepting it felt compromising. The loaner we agreed to instead came in a branded drawstring bag, which was accompanied by a sleek black storage box. Though I’d secretly hoped for the horsehair model, the kippah Hirsch sent was more utilitarian: a ribbed velvet, golden brown, with the rise and structural integrity of one of those dome-houses you see in Architectural Digest. Velvet piping twisted around its circumference; its cloth inner lining depicted a globe and a shofar.
I put it on.
Skullcap semiotics

The story of the kippah begins in the Talmud, when 3rd-century sage Rav Huna proclaimed that he never walked more than four cubits without his head covered to symbolize that the divine presence was always above him. After rabbinic law codified the practice in the 1500s, the kippah evolved into a marker of Jewish cultural mores.
For example, 20 years ago, most Modern Orthodox boys wore black suede kippahs, but today, as people debate whether Modern Orthodoxy is dead, suede is disappearing, replaced by black velvet, the standard among Haredi Jews, and the kippah sruga — the crocheted yarmulke associated with the Israeli Religious Zionist movement. Pluralism out, orthodoxy in.
But it’s also a fraught moment to be displaying any marker of Jewish identity. Wearing a kippah in public makes you subject to a certain type of attention these days: the glare of being Jewish at a time when the Jewish state is embroiled in enormously unpopular and destructive wars. Hirsch, who is 29 and lives in Berlin, knows this firsthand — these days he doesn’t feel safe wearing a kippah in public.
And yet I suspect that growing Jewish isolation also puts the lie to our assimilation fantasies; it makes us more likely to wear the things that attach us to each other. Indeed, there is a renaissance in Judaica today driven by new designers and younger consumers finding joy in their heritage. The name Rubenstein is a play on Hirsch’s middle name, Reuven. But he also just thought it sounded cool.
All about the Benyamins
First ironically, then with some resignation, I found that the Rubenstein was the only kippah I wanted to wear — my fancy kippah became my everyday kippah. Putting it on was a daily treat — I was humored by the upgrade. I began picturing how gloomy and shallow life would be without it. I debated the unthinkable — ponying up to keep the loaner.
I was still conflicted about the idea of the object, which felt like a metaphor for the sticker-shock that accompanies Jewish life, especially Orthodox life, in the U.S. today. There’s the skyrocketing cost of real estate in Jewish neighborhoods, the eyewatering day school tuition, even the price of kosher meat and grape juice. Was it an $85 kippah, or a yeshiva-league Sorting Hat?
I put the questions to Hirsch. There are very few ritual objects, he pointed out, from the kiddush cup to candlesticks to one’s tallit, that we pride ourselves on buying cheap. Why should kippot be the exception? “You’re giving your humility a bigger meaning,” he said, “by the fact that you’re wearing this on your head.”
It was true — I felt more humble than ever before, and expected others to acknowledge my commitment and my sophistication. I can see you are a man of taste, they would say, presumably lowering a monocle. (I would nod, then dip my double-dark chocolate Milano cookie into a steaming teacup.)
It was true my designer yarmulke was not the conversation starter I’d anticipated. Only one person complimented me on it unprompted — that singular infallible judge of quality, my mother. Everyone else, I’m certain, was stealing covetous glances. But they didn’t need to praise, ask about, or even notice my beloved yarmulke, which I’m sure I’ll return soon. The premium fabrics, the shofar in the lining and the devotion it all symbolized were between me and Hashem.

How Iran is outsourcing terror plots against Jews
The prosecution of an Iraqi national in connection with thwarted alleged terror plots in the U.S. and Europe has put the behind-the-scenes role of Iran in the spotlight — part of what security experts say is a growing and hard-to-trace threat.
Mohammad Baqer Saad Dawood Al-Saadi, a 32-year-old Iraqi national accused of ties to an Iran-backed militia, pleaded not guilty in Manhattan federal court this week to charges linking him to a series of attacks and alleged terror plots targeting American interests and Jewish communities in Europe and the United States.
Prosecutors allege Al-Saadi was connected to attacks, including the stabbing of two Jewish men in London’s heavily Jewish Golders Green neighborhood and an arson attack on a synagogue in North Macedonia. They also accuse him of attempting to recruit individuals online to firebomb synagogues in New York, Los Angeles and Scottsdale, Arizona.
He also reportedly planned to attack Ivanka Trump, who is both the president’s daughter and an Orthodox Jew — making her a “double target,” in the words of Oren Segal, vice president at the Center on Extremism at the Anti-Defamation League.
Iranian attacks on Jewish and Israeli institutions abroad are not new. Since the 1979 Islamic Revolution, Iran and its proxies have targeted diplomats, Jews, Israelis, political dissidents and others perceived as aligned with the West.
Matthew Levitt, director of the Counterterrorism and Intelligence Program at the Washington Institute for Near East Policy, maintains a detailed database of such attacks. He told the Forward that since the current war began, such plots have significantly increased.
The Al-Saadi case is a prime example of what Levitt calls Iran’s “gig economy” model of terrorism. Rather than dispatching trained operatives directly from Iran, Iranian-linked actors and proxy groups are recruiting individuals online who live in the country they wish to target. Some are not even aware they are attacking on behalf of Iran or its proxies.
In court filings, prosecutors allege that Al-Saadi, who prosecutors link to the terror organization Kata’ib Hezbollah and Iran’s Islamic Revolutionary Guard Corps, sent maps and photographs of a prominent Manhattan synagogue and other Jewish institutions to an undercover agent he was attempting to recruit to firebomb them. He allegedly offered the agent $10,000 in cryptocurrency in exchange for carrying out the plot, and discussed whether the recruit should “set the place on fire” or use an improvised explosive device.
Iranian-linked operatives, who are either part of Iran’s security apparatus or within its network of terror proxies, reach out to potential recruits on encrypted platforms like Telegram.
According to Levitt, the operatives are ordered by “very senior” elements of the Iranian regime to find recruits. “It stretches the limits of credulity to think that plots like this in the United States could be done without very senior top-down instruction,” Levitt said. “These are not rogue actors.”
Those they manage to recruit online are often financially motivated, agreeing to carry out attacks like vandalism, surveillance, or assaults in exchange for cryptocurrency payments. Others appear driven by ideology or online radicalization. Over the years, Iran’s recruits have included teenagers as young as 13.
“These are inexpensive plots,” said Levitt. “It requires just a few people to sit at a computer and try to recruit people and direct people.”
For Iran, this method is particularly strategic amid wartime. “Iran can’t go toe to toe with the U.S. or Israeli militaries, but it can engage in these asymmetric plots to show that they can still reach out and touch us to increase the cost of continuing to prosecute the war and to make people feel afraid,” said Levitt.
By relying on online recruits and loosely connected operatives, Levitt says Iranian-linked actors can obscure their involvement and maintain reasonable deniability. The calculation, he explained, is that authorities will be satisfied with arresting and prosecuting the individual carrying out the attack, rather than blaming Iran. This allows Iran to limit the risk of direct military escalation with the United States while continuing to conduct operations against it.
The Online Battlefield
According to Segal, Iranian influence increasingly permeates online.
“The threat to Jewish communities right now is multidimensional — Iranian-linked plots, cyberattacks, online propaganda,” he said. “They’re all converging at once, making it one of the more complex threat environments for the Jewish community in a long time.”
For years, Iranian state media outlets such as Press TV have targeted Western audiences with antisemitic content, including Holocaust denial, claims that Zionists control world events and other extremist narratives. A 2023 report by the ADL and the Center for Countering Digital Hate found that Press TV receives roughly one million monthly visits, with more than half of its traffic coming from Western countries.
Segal said Iranian-linked propaganda networks also increasingly operate in online spaces that overlap with broader activist communities. One such example is Resistance News Network, a Telegram channel with over 150,000 subscribers frequented by members of pro-Palestinian activist groups like Students for Justice in Palestine. The channel is filled with official Hamas, Hezbollah, and Houthi propaganda that is then reshared by American activists on mainstream social media accounts.
“What that does is enable the exchange of ideas, of propaganda, and of narrative that we then see show up at actual events on the ground,” he said.
Segal argues that exposure to such propaganda can make recruitment efforts easier.
“Our concerns are not only from somebody who may have been placed here or somewhere in Europe,” said Segal, “but from individuals who are animated by the propaganda they ingest every single day.”
Levitt agreed, stating that rising antisemitic and anti-Israel sentiment since the outbreak of the Gaza war has created a larger pool of individuals who may view attacks on Jewish or Zionist targets as justified.
“A lot of people are going to be much more willing to do something … especially if it’s not actually killing someone, but fire bombing something and/or targeting property that has symbolic value,” he said.
But the threat is not limited to physical violence.
Since the war began, Segal said Iranian-linked cyberattacks have “gone into overdrive.”
He says Jewish organizations and media outlets have faced hacking attempts on their websites, while Jewish individuals have had their identities stolen, with personal information being exposed online in mass doxxing campaigns.
Many such attacks are conducted by Iranian hacking collectives. One of the most notorious among them is Iranian hacker group Handala Hackers, which has conducted several attacks against Jews, Israelis and Americans. The FBI reported that in March, the group claimed to have stolen 851 gigabytes of confidential data from Sanzer Hasidic Jewish community members, which the hackers described as “documents of financial cooperation, witchcraft ceremonies, and secret correspondences with Netanyahu …” They added, “We warn the leaders and members of the Sanzer Hasidic community: No place is safe for you. Betrayal of the oppressed leads to nothing but disgrace and shame. Expect more documents to be revealed.”
Despite the growing number of plots, experts say the relative lack of successful attacks inside the United States reflects the effectiveness of American counterterrorism efforts.
Still, Jewish communities across the United States are investing heavily in security upgrades. Asher Lopatin, director of community relations at the Jewish Federation of Greater Ann Arbor, said synagogues in Michigan have increased security following a March attack on Temple Israel in West Bloomfield by a Hezbollah-linked man. Communities are installing bollards, expanding surveillance systems, and hiring additional guards.
“People are definitely doubling up on security,” Lopatin said. “Everyone is traumatized.”
Levitt says that even after the war concludes, he does not expect the plots targeting American interests and Jews to cease.
“I do not think that when the war ends, these necessarily stop,” Levitt said. “The pace may change, but Iran has a distinct interest in exacting revenge for all the damage that was done to it.”
