Wikipedia’s ‘Supreme Court’ tackles alleged conspiracy to distort articles on Holocaust
(JTA) — When a pair of professors earlier this month published a paper accusing a group of Wikipedia editors from Poland of revising articles to distort the history of the Holocaust, their research went viral.
Most academic articles are seen by dozens or hundreds of people at best. This one, published in The Journal of Holocaust Research, hit more than 27,000 pageviews within weeks.
The paper’s reach was fueled by its analysis, unprecedented in the academic literature on Wikipedia, and its finding that a dedicated group has for some 15 years manipulated a source of information used by millions in ways that lay blame for the Holocaust on Jews and absolve Poland of almost any responsibility for its record of antisemitism.
The paper caught the eye of not just scholars and journalists but of the people in charge of resolving disputes over editing on crowd-sourced Wikipedia, the seventh-most popular website on the internet and one that is seen as the last bastion of shared truth in an ever-fracturing online environment.
Typically, disputes among Wikipedia editors are resolved through community consensus mechanisms, but occasionally those mechanisms fail and allegations are brought to Wikipedia’s Arbitration Committee, a panel of elected editors known as Wikipedia’s Supreme Court.
“Wikipedia is not exactly democratic but anarchistic in a way that actively discourages any sort of an authority coming to solve a dispute,” said Joe Roe, a veteran Wikipedia editor who served on the committee in 2019 and 2020. “The Arbitration Committee is a very limited exception.”
In this case, something especially unusual happened. The Arbitration Committee, or ArbCom, decided to look into the allegations without receiving a formal request to do so. No one could recall the committee taking such a step in its nearly two decades of existence.
“A myopic decision here could result in untold numbers of people being fed a distorted view of Jewish/WWII history, which could have very real consequences given the recent amplification of violently antisemitic rhetoric by mainstream public figures,” wrote a user named SamX in a public post about the case. “ArbCom needs to get this right.”
The article that triggered the opening of the case was published under the title, “Wikipedia’s Intentional Distortion of the History of the Holocaust.” It accused 11 current and former editors of intentional distortions to numerous articles relating to the Holocaust in Poland. The paper referred to the editors by their usernames but also provided their real names if they had publicly identified themselves on Wikipedia message boards.
“Due to this group’s zealous handiwork, Wikipedia’s articles on the Holocaust in Poland minimize Polish antisemitism, exaggerate the Poles’ role in saving Jews, insinuate that most Jews supported Communism and conspired with Communists to betray Poles, blame Jews for their own persecution, and inflate Jewish collaboration with the Nazis,” wrote co-authors Jan Grabowski, a historian at the University of Ottawa, and Shira Klein of the history department at Chapman University in Orange, California.
Normally, mistakes on Wikipedia, whether intentional or not, can be quickly fixed by experienced editors who deploy a set of rules regarding sourcing and style. But in this case, the alleged distortionists know Wikipedia’s mechanisms well enough to at least appear to follow the rules and are willing to spend time arguing with other editors who step in to intervene. It becomes harder to get to the truth because they work to discredit established historians and prop up fringe voices to create the semblance of a real-world debate over historical events, according to the article.
In one of the dozens of examples documented in the study, the alleged distortionists have tried to pass the self-published work of an antisemitic Polish writer named Ewa Kurek as a reliable source. Kurek has said that COVID-19 is a cover for an attempt by Jews to take over Europe and that Jews enjoyed life in Nazi ghettos. An editor named Volunteer Marek argued in a backstage conversation among editors that Kurek should be cited as any “mainstream scholar” would be. And another editor, working on an article about a 1941 massacre of Jews in Poland, added Kurek’s claim that minimized the number of Jewish victims and exonerated Polish perpetrators.

One thing the research didn’t discuss is what motivates these editors to invest so much time and effort into distorting Wikipedia. Klein said the omission was deliberate.
“We’ve been very careful not to make any assumptions on what drives them or what their politics are,” Klein said. “Instead, we’ve tried to focus just on what they’ve done, which is in the written record. And as we say in the article, we don’t see any evidence of them being tied to a government or being in the service of anyone else.”
Klein’s disclaimer obliquely points to a larger challenge around the historical record of the Holocaust in Poland. A central tenet of the country’s ruling Law and Justice party is defending the image of ethnic Poles and imposing nationalist narratives on the past, especially the period of World War II. While history shows that many Poles participated in the persecution of Jews, Poland’s nationalist right insists on portraying Poles only as victims or heroes.
In 2018, the Polish government passed what’s known as the Polish Holocaust Law, which makes it illegal to slander the Polish nation or blame the country for Nazi crimes. In practice, the law has served to censor scholars and chill debate.
Grabowski, Klein’s co-author on the paper, has for years sparred with the nationalist right over Poland’s historical memory. He sued a Polish group that accused him of publishing lies about Polish history in 2018, and in 2021 was ordered by a Polish court to apologize for his research before an appeals court ultimately overturned the order.
Domestically, Poland’s ultranationalists have largely won the war over the public discourse, which has freed them to focus on the global scene, where English-language Wikipedia is regarded as a major battlefront.
In this atmosphere, even something as basic as the background of Yiddish novelist and Nobel prize laureate Isaac Bashevis Singer can become fodder for debate. For years, Singer was at the center of a fight between two editors over whether Singer was best described in the first line of his Wikipedia article as a Jewish or Polish author. The eventual compromise — “Polish-born Jewish American” — lasted for almost two years until Feb. 23 when someone again dropped the “Jewish.”
The Wikipedia editors now being accused of distorting articles to further nationalist narratives have rejected the allegations against them.
“I have not engaged in any ‘Holocaust distortion,’ on Wikipedia or anywhere else. I am not a ‘right-wing Polish nationalist,’” said Volunteer Marek in a public comment on a Wikipedia message board that was endorsed by at least one other alleged distortionist. “I am not part of some nefarious ‘Polish conspiracy’ on Wikipedia which seeks to manipulate content. All of these accusations are ridiculous and absurd. They are particularly disgusting and vile since they go against everything I believe in.”
In the debate about how to handle the case, dozens of arbitrators and ordinary Wikipedia editors — all volunteers — spoke of the situation on a Wikipedia message board as something close to an existential crisis for Wikipedia. Not only was the website accused of being used to spread antisemitic propaganda, but it was also alleged to be vulnerable to large-scale manipulation by a small group of bad-faith actors.
There is little confidence in the community that a solution is within reach. By its own rules, the committee isn’t supposed to decide on disputed information. It’s more of a disciplinary body that evaluates the behavior of Wikipedia editors and can ultimately decide whether to restrict their editing privileges or ban them outright.
But figuring out if the accused editors have indeed evaded safeguards and undermined Wikipedia’s integrity would seem to require that the arbitrators become experts on the history of the Holocaust in Poland.
The decision to take up the case serves to acknowledge that the committee failed to solve the problem when it last considered complaints about editing related to the Holocaust in Poland about two years ago. That was during Roe’s tenure and he says the committee was distracted by another dispute at the time.
“It can’t be escalated further than it already has in our mechanisms,” Roe said. “The best we can do is what’s currently happening now — just put it through those mechanisms again, and hope that something better will come out on the other side.”
In explaining why the committee must nevertheless take on the case, an arbitrator who goes by Wugapodes commented that the only other choice is to kick the can down the road.
“This will not be an easy issue to resolve, but the committee was not convened to solve easy issues,” Wugapodes wrote, pointing out that the timing is right given the attention and involvement of outside experts and editors. “We can leverage these resources now or wait for this decade-long problem to get still worse.”
By a vote of nine to one on Feb. 13, the committee decided to open the case. The proceedings, which start with an evidence-gathering phase, are expected to last up to six weeks, after which they can decide to ban and restrict offending editors.
Beyond that, an unorthodox last resort option is also available. Wikipedia’s so-called Supreme Court could ask for help from an even higher authority: the Wikimedia Foundation, a nonprofit that owns the encyclopedia. The foundation intervened in 2021 in what some see as a similar scenario of a far-right takeover on the Croatian-language Wikipedia, hiring an outside expert to disentangle the web of obfuscation and banning a set of editors.
Roe said that his tenure on the committee in 2019 and 2020, which featured related complaints about the editing of articles on the Holocaust in Poland, helped lead him to believe that Wikipedia should embrace change, at least when it comes to controversial political topics.
“I would like to see these difficult and politically charged content problems be referred to a new body made up of external experts, and that we don’t insist on doing everything internally among the community volunteers,” Roe said.
But he acknowledged that such a scenario is unlikely to result from the Poland dispute.
“It’s not a popular view and it kind of goes against the general idea of Wikipedia,” he said.

Iran Expected to Ramp Up Chemical, Biological Weapons Programs

Amid sustained international scrutiny of Iran’s nuclear program, missile development, and regional proxy network, new assessments point to a quieter and more troubling front as allegations grow that Tehran may be expanding work related to chemical and biological weapons capabilities.
According to a new report from the Begin-Sadat Center for Strategic Studies at Bar-Ilan University in Israel, the Islamist regime in Iran may be advancing efforts to significantly develop its chemical and biological weapons programs — a move experts warn would pose serious risks not only to Israel but also to the wider region and the Iranian population itself.
Iran’s chemical and biological research programs allegedly focus on a range of toxic agents, including blister agents like mustard gas, nerve agents such as sarin and Novichok, and substances that attack the lungs or blood and can cause suffocation.
These reportedly also include biological threats such as anthrax, ricin, and botulinum toxins, as well as certain viruses, all of which can cause severe illness or death by disrupting the body’s nervous system, organs, or immune response.
Israeli officials have previously warned that the Iranian government has been developing dual-use chemicals, with both civilian and military applications, and may be channeling them to its regional proxy terrorist forces, raising fears they could be used to intensify proxy conflicts and destabilize the wider Middle East.
Tehran is also suspected of having used such agents to help suppress the nationwide anti-government protests earlier this year, which were violently crushed by security forces in a crackdown that left tens of thousands of demonstrators tortured, imprisoned, or killed.
Similar allegations have repeatedly emerged in the past, adding to a wider pattern of reported abuses against civilians and violations of human rights.
According to a report from Iran International, a medical staff member in Karaj said some detainees released during the January protests had reported body aches, lethargy, weakness, loss of appetite, nausea, and vomiting — all symptoms that may indicate possible drug-related poisoning.
Iran first began developing chemical weapons-related capabilities in the 1980s. In recent years, those efforts have reportedly evolved to include pharmaceutical-based agents and other compounds designed for incapacitation or riot control.
US government assessments have indicated for decades that Iran has been researching and developing chemical agents, including anesthetic compounds designed to incapacitate individuals by targeting the central nervous system.
These reports point to Iran’s academic sector playing a key role in this area, with Imam Hossein University and Malek Ashtar University of Technology — military-linked institutions associated with the Islamic Revolutionary Guard Corps and the Ministry of Defense — reportedly conducting research since at least 2005 into chemical agents designed for incapacitation.
Since the start of the war earlier this year, the Israeli Air Force has carried out sustained strikes targeting sites linked to chemical weapons research, development, and production, aiming to disrupt facilities embedded within Iran’s broader military-industrial infrastructure and associated pharmaceutical-based programs.
Even though Tehran has long denied pursuing chemical or biological weapons and remains a party to the Chemical Weapons Convention, Western governments continue to accuse the regime of violating international norms.

Germany Reports ‘New Normal’ of Antisemitism as Islamist and Left-Wing Extremist Networks Fuel Rising Threats
Graffiti reading “Kill all Jews” was discovered on a residential building in Berlin-Pankow on April 26, 2026, part of a wave of antisemitic vandalism reported across the German capital over the past week, including swastikas and other hate-filled slogans scrawled on multiple sites.

Germany is confronting what Jewish leaders describe as a “new normal” of antisemitism, with nearly half of Jewish communities across the country reporting incidents and officials warning that Islamist and left-wing extremist networks are driving a surge in hostility amid ongoing Middle East tensions.
According to a new survey released on Friday by the Central Council of Jews in Germany, 46 of more than 100 Jewish communities nationwide have been targeted in antisemitic incidents, underscoring the growing scale and urgency of the crisis.
Among the most commonly reported incidents were verbal abuse, threatening phone calls, hate speech, property damage, and antisemitic graffiti, with 68 percent of respondents saying they feel “very unsafe.”
“Following the explosive rise in antisemitism after Oct. 7, a ‘new normal’ has emerged,” Central Council President Josef Schuster said in a statement, referring to the Hamas-led invasion of and massacre across southern Israel over two years ago.
“A situation in which Jewish communities require constant protection and antisemitism has become normalized as part of the public sphere,” he continued.
In the wake of the recent war with Iran, 62 percent of respondents said their sense of insecurity has further intensified.
“This finding clearly shows that the war in the Middle East was always just a pretext, never a reason for antisemitic attacks and hate speech in Germany,” Schuster said.
Only 35 percent of respondents reported feeling a sense of solidarity and support from broader society, underscoring a widespread perception of isolation.
Even though religious and communal life continues largely with only minor restrictions in most communities, many Jews increasingly avoid displaying visible signs of their identity in public.
“Things that used to be taken for granted — openly wearing religious symbols, walking carefree to the synagogue — are now often accompanied by caution and more conscious consideration. At the same time, the emotional strain has increased significantly,” said one unnamed survey participant, according to the Central Council.
Amid a sharply deteriorating security climate in Germany, officials warn that surging antisemitism and hostility toward Israel are increasingly being driven by Islamist networks and left-wing extremist groups, with threats against Jewish and Israeli communities intensifying nationwide.
According to a study by the Hessian State Office for the Protection of the Constitution, Islamist and left-wing extremist actors are exploiting the Middle East conflict and rising regional tensions to spread antisemitic rhetoric, contributing to an increase in violence and harassment against Jews and Israelis.
The newly released report warns that such antisemitic narratives have become a central mobilizing force since the Oct. 7 atrocities, shaping public discourse and being used to justify acts of violence and intimidation.
“Antisemitism is no longer an isolated phenomenon, but a cross-cutting issue that connects various extremist groups,” the study notes.
After more than two years of escalation, German officials warn that the threat to Jewish life has risen dramatically, with antisemitic hate speech surging as extremist actors deliberately exploit the war in Gaza for propaganda.
The report points to extremist groups merging anti-imperialist ideology with entrenched antisemitic narratives in their propaganda around the Israel–Hamas war, including claims of a “genocide in Gaza,” depictions of the Jewish state as a “colonial power,” and labels such as “child murderer.”
These narratives are being used to justify violence against Israel and to exploit the humanitarian crisis to increase hostility and advance their agenda.
German Interior Minister Roman Poseck, who commissioned the report, warned of a deteriorating social climate, saying that “antisemitic sentiments are becoming increasingly intolerable, even in public spaces.”
“Antisemitism is one of the greatest threats to our social cohesion – especially from Islamism and the left-wing extremist spectrum,” the German official said in a statement.
“I am deeply ashamed of what Jews in Germany have to endure 80 years after the end of the Second World War,” he continued. “We Germans, in particular, bear a lasting responsibility never to forget what happened.”
According to Germany’s Radicalization Monitoring System and Transfer Platform, 45 percent of Muslims under the age of 40 in the country show an inclination toward Islamism — defined as support for Islamist ideas, preference for Sharia-based principles over the constitutional order, and the presence of antisemitic prejudices.
Among those surveyed, 23.8 percent view an Islamic theocracy as the most desirable form of government.
Even though right-wing extremism may be less normalized in mainstream discourse, the study warns it “remains a danger, as antisemitic prejudices and conspiracy myths continue to be deliberately spread there as well.”
The western German state of Hesse has seen a particularly visible surge in antisemitic expression, with chants such as “Child-murderer Israel,” “From the river to the sea,” and “Resistance is international law” heard at pro-Palestinian demonstrations, across social media, and on university campuses.
The study notes that these narratives act as a unifying thread, bringing together Islamist, left-wing, and right-wing extremists who adopt similar rhetoric to reinforce shared enemies and legitimize violence.
Notably, the German Left Party has repeatedly been at the center of controversy and public outrage over its continued use and promotion of anti-Israel rhetoric, reinforcing a recurring pattern of incidents within its ranks that have sparked allegations of antisemitism.
Last year, the party’s youth wing passed an anti-Israel resolution labeling the world’s lone Jewish state a “colonial and racist state project.”
More recently, Andreas Büttner, the commissioner for antisemitism in the state of Brandenburg in northeastern Germany, resigned from the Left Party, citing a rise in antisemitism within the ranks, relentless personal attacks, and a party climate that has become intolerable.
Beyond extremist circles, the report also points to antisemitism extending across segments of society, finding resonance in mainstream discourse where it is often disguised as legitimate criticism of Israel.
“This is shifting the boundaries of what society considers acceptable, normalizing antisemitic thinking while trivializing, legitimizing, and in some cases even glorifying violence against Jews,” the study says.
Earlier this month, the Hesse government introduced new legislation that would criminalize denying Israel’s right to exist, as authorities move to confront a surge in anti-Israel demonstrations and a growing tide of antisemitic rhetoric and attacks that have intensified pressure on Jewish communities across the country.
The proposed legislation would close what officials describe as a legal loophole by explicitly criminalizing the denial of Israel’s right to exist, with penalties of up to five years in prison or a fine, aligning it with existing provisions that punish Holocaust denial.

Hasan Piker Campaigns With Pennsylvania Democrat as Star Rises Despite Antisemitism Controversies

Tensions in Philadelphia intensified this week after Pennsylvania state Rep. Chris Rabb, a Democrat running for US Congress, appeared on a livestream hosted by far-left commentator Hasan Piker, drawing criticism from political opponents and some Jewish community leaders over Piker’s expressed hostility toward Israel and support for foreign terrorist groups such as Hamas and Hezbollah.
Rabb, who is seeking the Democratic nomination in Pennsylvania’s 3rd Congressional District, joined Piker’s widely watched online broadcast as part of an effort to reach younger, digitally engaged voters. The district, a safely Democratic seat centered in Philadelphia, is expected to be decided in the primary, where Rabb faces a competitive field that includes state Sen. Sharif Street and physician Ala Stanford.
Piker arrived in Philadelphia from Los Angeles to help Rabb fundraise for the campaign and joined him for a rally. While talking with Piker on the livestream, Rabb addressed backlash over his decision to meet with the streamer, dismissing his critics as being motivated by racial animus.
“I’m going to be slammed for even talking to you,” Rabb told Piker. “But there’s a double standard, because as a Black progressive, I can’t do this. I’m part of the problem or whatever.”
During the livestream, Rabb discussed progressive policy priorities and his campaign message. But the appearance quickly became a flashpoint in the race, as critics pointed to Piker’s history of inflammatory comments.
“Hasan Piker has a documented record of statements that we find deeply troubling,” said Jason Holtzman, chief of the Jewish Community Relations Council at the Jewish Federation of Greater Philadelphia. “He dismissed the sexual violence of [Hamas’s attacks on Israel on Oct. 7, 2023]. He called Orthodox Jews ‘inbred.’ He compared Zionists to Nazis. He characterized Hamas as preferable to the state of Israel.”
Holtzman added, “These are not edgy opinions. They are statements that minimize Jewish suffering, dehumanize Jewish people, and normalize violence against Jews and the Jewish state.”
Since entering the race, Rabb has attempted to establish the Israel-Hamas conflict as a central feature of the competition. He has lambasted his opponents for stopping short of accusing Israel of committing “genocide” in Gaza and has repeatedly pressed other Democrats on where they stand on the conflict.
Ala Stanford, an establishment Democrat who is widely considered the favorite in the race, has refused to accuse Israel of “genocide” and has stated that such accusations are harmful to the local Jewish community.
Piker, a prominent left-wing streamer with a large following on platforms like Twitch, has previously drawn backlash for rhetoric which critics say crosses into antisemitism. In addition to repeatedly praising Hamas, he has even said “it doesn’t matter” if sexual assault took place during the terrorist group’s Oct. 7, 2023, invasion of and massacre across southern Israel.
This week, US Reps. Josh Gottheimer (D-NJ) and Mike Lawler (R-NY) introduced a bipartisan resolution that condemns “antisemitic, hate-filled rhetoric and content” promoted by Piker and podcaster Candace Owens.
Piker has denied accusations of antisemitism.
“They are once again conflating legitimate critics of Israel with actual antisemites,” he told the Jewish Telegraphic Agency (JTA) in response to this week’s resolution in Congress. “They would rather complain about fake antisemitism in defense of Israel than call out the real sources of Jew hatred with a full chest. I have spent my entire career combating all forms of bigotry including antisemitism and will continue to do so in spite [of] this cynical ploy to satisfy donors.”
Most recently, Piker has come under fire for praising Graham Platner, the presumptive Democratic nominee for US Senate in Maine, for previous Reddit comments in which he complimented Hamas.
During Thursday’s rally in Philadelphia, Piker urged the crowd to help Rabb secure the congressional seat instead of a “do nothing Democrat” who would not accuse Israel of committing “genocide” in Gaza.
The controversy underscores how the Israel-Hamas conflict has become a defining issue in Democratic primaries across the country, exposing deep divisions within the party. In Philadelphia, where there is a significant Jewish population, candidates have faced increasing scrutiny over their positions and associations. However, the district, which is disproportionately Black and lower income, is unlikely to be heavily swayed by the conflict in Gaza when considering their vote.
Rabb’s campaign defended Piker’s appearance, framing it as an effort to broaden political participation and engage younger voters who consume news and commentary online rather than through traditional media outlets.
Further, the episode highlights a broader shift in campaign strategy, as candidates increasingly turn to digital influencers to expand their reach. But it also illustrates the risks of entering highly polarized online spaces, where associations can quickly become liabilities.
Over the past few weeks, Piker has traversed across the country, appearing alongside a litany of rising progressive stars during fundraisers and rallies. Recently, he appeared at the University of Michigan alongside the controversial Senate candidate Abdul El-Sayed. Similar to Rabb, El-Sayed has accused Israel of “genocide” in Gaza. The Senate candidate has also come under criticism for seemingly sympathizing with a Hezbollah-linked terrorist who attempted to attack a Michigan synagogue in March.
