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.

Recorded anti-Jewish hate crimes rise 10% in England and Wales
(JTA) — Hate crimes targeting Jewish people in England and Wales rose by 10% in the year ended in March, according to the latest data released by the British government.
Police-reported hate crime — including crime influenced by other factors such as race and sexual orientation — overall increased by 7% compared with the previous year, according to the Home Office data released last week.
British Foreign Secretary Ed Miliband posted on X on Monday, “Antisemitism has no place in our society. This morning, I hosted a crucial discussion with the J7 Global Task Force to discuss how we can work together across countries to stamp out the scourge of antisemitism.”
Following the meeting, the Board of Deputies of British Jews issued a statement explaining that Miliband and the task force had discussed, among other things, “the sharp rise in global antisemitism” and the “continued demonisation of Israel.” Representatives from the U.K., the U.S., Canada, Germany, France, Argentina and Australia make up the task force.
“In the meeting, the J7 proposed a new international intergovernmental ministerial task force on antisemitism, comprising the countries represented in the J7 and taking on the key themes discussed. We were pleased that the Foreign Secretary agreed to host an inaugural meeting of J7 countries’ ministers to start this process,” the statement sent to JTA said.
The Community Security Trust, a charity that protects the Jewish community and monitors antisemitism, said on X that the new data show “that antisemitic hate crime remains at an unacceptably high level.”
“As seen previously, Jewish people continue to experience by far the highest police-recorded rate per head of religious hate crime of any faith group,” CST said. “This shows the disproportionate scale of anti-Jewish hatred and its impact on Jewish life in Britain.”
Religious hate crime rose by 13% overall in the 12 months to March 2026, the report said. The overall figure rose from 10,067 to 11,419 offenses.
The two groups most affected were Jews and Muslims, the Home Office said. Religiously motivated hate crimes against Muslims increased 15%, the report found, with spikes reported around public protests in September 2025 and the start of the U.S. war with Iran in February.
The number of recorded offenses affecting Jews rose from 2,874 to 3,162 offenses, spiking after the attack on Heaton Park synagogue in Manchester last year on Yom Kippur.
Two men, Melvin Cravitz and Adrian Daulby, were killed on Oct. 2, 2025, after Jihad Al-Shamie, who was wearing a fake suicide bomb belt, drove into the gates of Heaton Park synagogue and began attacking congregants with a knife. Cravitz died from stab wounds; Daulby was fatally struck by a police bullet during the response.
A spate of violent antisemitic incidents followed this year, including the torching of four ambulances belonging to Jewish volunteer service Hatzola on March 23 and the stabbing of two Jewish men in separate attacks in Golders Green on April 29.
The Home Office figures, which do not include data from London’s Metropolitan Police Service because of a change in how it records crime, showed the second-highest level of religious hate crime directed at the Jewish community since the Home Office began keeping records in 2018. It was surpassed only by the year ending March 2024.
“In the last year, there were 117 police recorded religious hate crimes targeted at Jewish people per 10,000 population, the highest rate for any religious group. The next highest rate was for religious hate crimes targeted at Muslims, with 13 per 10,000 population,” said the Home Office.
The report was published on Oct. 8, at a time of heightened sensitivity. Eleven people were arrested at pro-Palestinian marches in London a day earlier, despite calls by the Metropolitan Police to avoid demonstrating on the anniversary of Hamas’ deadly 2023 raids inside Israel.
Police reported 20 arrests at Saturday’s pro-Palestinian protest in London, where many demonstrators were wearing kaffiyehs, waving Palestinian flags and brandishing banners.
The level of hate directed at the Jewish community has remained at an “elevated level” since the beginning of the Israel-Hamas conflict, the report stated.
The CST said, “There is an urgent need to reduce the amount of incitement connected to conflict overseas,” adding that “much more needs to be done across society to tackle this problem.”
Over the summer the government announced a major funding boost to support the Jewish community, promising £250 million ($335 million) over the next three years for increased policing and protection of Jewish communities.
More remains to be done, according to community organizations.
A spokesperson for the Board of Deputies of British Jews said the report’s publication “confirms the need for rigorous prosecution to ensure deterrence, and a whole of society approach to tackling hatred and extremism, and to stopping conflict in the Middle East being used to incite hatred against the Jewish community.”
The Campaign Against Antisemitism said the report was evidence that the British justice system was failing the Jewish community.
“Antisemites, emboldened by the Hamas terrorist atrocity three years ago, are not only not letting up in their hatred but are doubling down,” it said in a statement. “That’s because there is no real deterrent. So really these figures are most damning for the criminal justice system, which has utterly failed to defend British Jews.
“Even as conflict in the Middle East is easing off, antisemitism in the U.K. is rising, yet there have been essentially no changes in policing policy over the past three years and nobody has been held to account for this monumental failure,” the campaign said.

Hasan Piker criticizes ‘opportunists’ who accused Mamdani of genocide
(JTA) — Hasan Piker called the protesters who jeered New York Mayor Zohran Mamdani at an Oct. 7 vigil last week “opportunists,” who “tarnished” the anti-Zionist movement’s message.
Piker, the popular streamer who has campaigned for a number of democratic socialist candidates, made his remarks Sunday at Jewish Currents Live, an all-day event hosted by the left-wing magazine at the Brooklyn Academy of Music.
Speaking on a panel titled “Can the Left Wield Power?”, he said that the protesters had “valid concerns,” including demands like firing police commissioner Jessica Tisch and disbanding the NYPD’s Strategic Response Group, a heavily armed unit that often responds to protests.
But he criticized the Democratic Socialists of America — the left-wing political organization that Mamdani has called his “political home” — for not playing a bigger role in last week’s protest, which started at City Hall and later overran an Israeli peace vigil. DSA did not sponsor the protest, though some campus chapters of its student section, the Young DSA, participated.
“The DSA not being at the forefront of the anti-Zionist mobilization in New York City is what allowed that mobilization to be tarnished by opportunists, sectarians and those who actually were calling him a genocidaire — which I obviously find to be ridiculous,” Piker said, referring to protesters’ chants of “Mayor Mamdani you can’t hide, we charge you with genocide.”
Piker, who has drawn heat for his anti-Israel views, did not comment on the Hamas iconography displayed by numerous protesters, nor the decision to crash an Oct. 7 vigil that memorialized the 1,200 people killed in the Hamas-led attacks on that date in 2023, and the 74,000 Palestinians who have been killed since then, according to Gaza health ministry figures, which do not distinguish civilians from combatants.
Separately, Mahmoud Khalil, the Columbia University pro-Palestinian protest leader who was detained by ICE last year, reportedly criticized those protesters’ “purity politics” during an event in Washington, D.C.
“You don’t have to agree with someone 100 percent — 85 percent is good,” he said, provided that the end goal is “liberating Palestine and ending the unconditional support of the United States.”
Where should Democrats draw the line?
Two Democratic congressional nominees from New York, Brad Lander and Darializa Avila Chevalier, appeared on a separate panel focused on Israel and the Democratic Party.
Lander is Jewish and Darializa Avila Chevalier helped lead Columbia University’s pro-Palestinian encampment in 2024. Peter Beinart, editor-at-large at Jewish Currents, moderated the panel, which also featured Georgia state Rep. Ruwa Romman, the first Palestinian American elected to public office in her state.
Their discussion exposed some of the gaps between Lander and Avila Chevalier, both progressives who were endorsed by Mamdani this year and who appeared in a campaign ad together alongside fellow Mamdani endorsee Claire Valdez.
Beinart asked where Democrats should draw the line on what is considered legitimate Palestinian resistance. He pointed to the pro-Palestinian protest held in New York City on Oct. 8, 2023, which Avila Chevalier attended and Lander called “abominable” at the time.
“I think international law has already drawn that line,” Avila Chevalier said, arguing that U.S. protests should target Israel, which receives U.S. support, rather than Hamas.
“We could be the biggest anti-Hamas protesters, but a protest against Hamas in the U.S. isn’t going to do anything,” Avila Chevalier said. “Because we don’t fund it. We don’t have any structural power over it, there is nothing tying us to that institution other than condemning it endlessly.”
After the event, Lander did not confirm to the Jewish Telegraphic Agency whether he had spoken about that Oct. 8 protest with Avila Chevalier.
“We have talked about these issues broadly in private, and I don’t want to characterize those conversations,” Lander told JTA. “And obviously I’ve made my feelings known in public, and I stand by them. I mean, on that day, I was in mourning.”
An attendee named Mark, 29, who declined to share his last name to avoid potential workplace complications, said he felt that Avila Chevalier “didn’t really acknowledge the criticism about perhaps disregarding loss of life; despite the power imbalance, it is lost life.”
For Lander, meanwhile, Mark said it was “politically expedient” for him to not directly address Avila Chevalier’s presence at the 2023 protest. “This is a super lefty crowd that probably would eat him alive if he went against her right now,” he said.
During the panel, Avila Chevalier repeated her call for an arms embargo against Israel while Lander stopped short of doing so, consistent with his statements in the past that Israel should be able to buy defensive ware. Both said Congress must pass the Block the Bombs Act and vote to suspend the sale of offensive U.S. military weapons to Israel. Lander was the only speaker on stage who advocated for a two-state solution in the region.
Beinart asked Romman about Jon Ossoff, the Jewish Democratic senator running for reelection in her state, and how she views his stance on Palestine. She said she was pleased that both Georgia senators have been consistently voting in favor of Bernie Sanders’ resolution to block arms sales to Israel, but added that “in terms of leading, in terms of rhetoric, there’s still a lot of work to be done.”
“We’ll get everyone to where we need them to be eventually,” she said.
‘The bund is back in town’
The Jewish Labor Bund — the early 20th-century socialist movement that fought against Bolshevism, Nazism and Zionism — came up at numerous points on Sunday. One attendee doled out fliers with a website URL and the message, “Tell your bubbe the bund is back in town.” It was also a subject of a conversation that featured Molly Crabapple, whose 2026 book “Here Where We Live is Our Country” focuses on the Bund.
Arlene Geiger, an Upper West Sider and longtime activist, told JTA that she related to those conversations.
“My connection to Judaism is not to Israel, it never has been. It’s more to Eastern Europe and the Bund, so that spoke to me,” Geiger said.
Mark, who is from New Jersey, said he doesn’t come from a “staunchly pro-Zionist” family, but that he has a new interest in leftist Jewish spaces since realizing that he could no longer comfortably distance himself from the issue of Israel, which he believes is committing a genocide.
“It’s just an education for me to be immersed in this kind of space,” he said.

In Israel, boy killed, hikers injured, after suspected Hezbollah cluster bomb detonates
(JTA) — An explosion during a school hiking trip killed a boy about 14 years old on Monday and injured 24 others in northern Israel, Magen David Adom, Israel’s emergency medical service, said.
Rescue teams were dispatched to the scene, and the injured were evacuated to hospitals in northern Israel.
“An initial investigation by IDF forces at the site indicates that it was likely a cluster bomb belonging to the Hezbollah terror organization that had been left in the area and exploded,” the military said in a statement.
“The injured were scattered along the route, some trying to help their wounded friends,” explained David Radko, an MDA medic who said he was the first to arrive on the scene. “Despite the horrific scenes and distress, the injured cooperated with me exceptionally well. Everyone tried to help their friends as much as they could. Some even applied tourniquets to their friends to stop the bleeding.”
Police Commissioner Danny Levy visited the scene and said authorities may ban similar school trips in the near future. “We need to examine whether we are putting students at risk by allowing them to go on these trips,” he said.
Tamir Douadi, a resident of Kibbutz Manara, described the scene in a voice cracking with emotion to Channel 12: “Look, they’re young people, children. You see them sitting there like that, holding their friends.”
The object exploded “in the hands” of one of the schoolchildren, Comm. Meir Eliyahu, commander of the Israel Police’s Northern District told reporters at the scene.
Orly Ben Simon, an MDA paramedic, said personnel identified several people with injuries of varying severity, including a 14-year-old boy who was unconscious and in critical condition. “We immediately began prolonged and intensive resuscitation efforts. Unfortunately, his injuries were critical, and we had to pronounce him dead at the scene,” she said in a statement provided by the MDA.
She added that medical teams treated two teenagers who were seriously injured, as well as other injured people who were able to walk.
In an initial statement, the Ma’alot-Tarshiha municipality said the explosion occurred during an annual hiking trip by students from the ORT Ma’alot religious high school, located in the mixed Jewish-Arab town, about five miles from the Lebanese border. The entire area has come under heavy fire from Hezbollah since Oct. 7, 2023, and some of the munitions have failed to detonate.
MDA said the injured included 22 teenagers and two adults in their 50s. Two of the injured were in serious condition and 10 were in moderate condition. They were evacuated by ambulance and helicopter to hospitals in Haifa, Safed and Nahariya.
Israel’s Education Ministry described the incident as “extremely serious.” According to the ministry, the trip was properly approved in accordance with established procedures. Ma’alot-Tarshiha Mayor Moti Ben David told Israeli media that the route was a popular hiking trail.
