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.

Milei praises ‘Judeo-Christian values’ at Chabad event as Argentina courts European Jews
(JTA) — BUENOS AIRES — Argentine President Javier Milei exalted “Judeo-Christian values” on Monday as he spoke to a crowd of 1,800 people celebrating the 32nd anniversary of the death of the last Chabad-Lubavitch rabbi.
Milei was the keynote speaker at the Hasidic Orthodox movement’s event marking the yahrzeit of Rabbi Menachem Mendel Schneerson, becoming what appears to be the first sitting non-Jewish head of state to make an official tribute to the Lubavitcher Rebbe at a major Chabad event.
“The conclusion I have reached is simple in its formulation and profound in its consequences: When one embraces Judeo-Christian values, spiritual and material life become aligned and resonate on the same wavelength,” Milei said Monday night at the Palacio Libertad cultural center.
It was the latest in a long list of expressions of admiration for Judaism for Milei, a self-described “anarcho-capitalist” who was elected in 2023 and since has made support for Israel a cornerstone of his agenda. He has previously visited Schneerson’s grave in New York City, made pilgrimages to the Western Wall in Jerusalem and presented a picture of Schneerson to Israeli Prime Minister Benjamin Netanyahu as a gift. He was also honored at a Chabad synagogue in Miami in 2024, where he revealed that he believed he has Jewish heritage.
Milei has long studied Judaism and has said he wants to convert after leaving office but sees Jewish practice, including the observance of Shabbat, as incompatible with the presidency.
His 40-minute speech at the Chabad event focused almost entirely on Jewish religious texts and thought, quoting passages from the Torah as the basis of his economic view.
Milei also revealed that his address was drawn from the epilogue of his upcoming book, “Morality as State Policy,” in which he argues that capitalism is a system invented by “the Creator” — whom he also referred to as “the One” — to bring paradise to earth through work.
Jews in Argentina have a range of perspectives on Milei’s philosemitism.
“I appreciate that the president chose to attend and speak at the Tribute to the Rebbe,” Rabbi Tzvi Grunblatt, the head of Chabad in Argentina, told the Jewish Telegraphic Agency. “He is doing so from a deeply personal place. I also think it is healthy for him to have this spiritual side.”
But Alicia Osipovich, a sign-language interpreter assisting a deaf attendee at the event, told JTA that Milei’s forceful support for Israel and Judaism made her uneasy, even as she personally appreciated it.
“I’m proud and deeply moved to have a president like him,” Osipovich said. “At the same time, I have some concerns. He speaks extensively about Israel, and you know how support for Israel is sometimes portrayed. He says he is a Zionist, but nowadays the word ‘Zionist’ is often used as a negative label. I have mixed emotions. As a Jew, I am proud, but I also feel some concern about the increased public exposure of Judaism these days.”
Under Milei’s leadership, Argentina has invited European Jews worried about rising antisemitism to consider the country as a destination. Foreign Minister Pablo Quirno recently emphasized Argentina’s attractiveness in a message aimed at Jews in Britain and other European countries who are grappling with surging incidents targeting Jewish communities.
“A country on the up with great opportunities. Sunny, with many natural attributes, and home to the largest Jewish community in Latin America. Strong stand against antisemitism. British and European Jews should seriously consider Argentina. You are welcome,” Quirno wrote on X in reply to author Saul Sadka, who had urged British Jews to consider leaving amid growing hostility.
Argentina’s leading Jewish organization, DAIA, has recorded more antisemitic incidents in recent years, mostly taking place online. But the rate of antisemitic incidents reported in the country last year was significantly lower than in many other countries with sizable Jewish populations, according to the 2025 worldwide antisemitism report published in April by Tel Aviv University.
Rabbi Abraham Cooper, the Simon Wiesenthal Center’s global director, praised Quirno’s invitation, saying it reflected a significant shift.
“Sign of the times? A country formerly ruled by a Nazi-supporting dictator has morphed over decades into a strong democracy whose president is a philo-Semite,” Cooper wrote in reply to Milei’s foreign minister. “Argentina currently serves as chair of IHRA [the International Holocaust Remembrance Alliance]. Foreign minister now beckons embattled British Jews. Incredible.”
Israel’s ambassador to Argentina Eyal Sela told JTA at the Chabad event that he had no difficulty recognizing that Argentina is currently a very good place for Jewish life.
“Yes, I agree with the Argentine foreign minister,” Sela told JTA. “Of course, Israel will always be the best place for Jewish life. But today, Argentina is a much better place for Jews than Europe.”
Monday’s event opened with the testimony of Yosef Chaim Ohana, a survivor of the Oct. 7, 2023, Hamas attack on Israel, who expressed deep gratitude for the support shown by Jews around the world, followed by remarks from his father, Avi Ohana. Milei hosted the Ohanas and Grunblatt on Tuesday morning at Argentina’s presidential palace, the Casa Rosada.
Dozens of Argentine nationals were murdered or taken hostage on Oct. 7. This week, an Israeli who had worked in Buenos Aires at the Israeli embassy in Argentina was killed in an attack on a moshav in central Israel.

France bans Smotrich as 6 countries impose new sanctions over Israeli settler violence
(JTA) — Six countries have imposed coordinated sanctions against Israeli groups over settler violence in the West Bank, with France barring Israel’s far-right finance minister, Bezalel Smotrich, from its borders.
France, the United Kingdom, Canada, Norway and Australia on Tuesday released sweeping sanctions on Israeli networks and leaders to “hold extremist settlers accountable for the horrific levels of settler violence against Palestinian civilians,” their foreign ministers said in a joint statement.
The measures include a range of travel bans and asset freezes aimed at disrupting flows of finance to extremist settler groups as violence escalates in the West Bank. The United Nations reported over 1,800 settler attacks against Palestinians in 2025, the highest number since it began documenting incidents in 2006, and violence has remained intense this year. The Israeli military also recorded a sharp increase in nationalist and settler violence in 2025.
Israel said it rejected “the disgraceful measures adopted by foreign governments against Israeli citizens, entities, and a government minister,” accusing the other countries of imposing a political stance that was “camouflaged as measures against violence.”
“What these governments have in common is their resounding failure to combat the antisemitism that is rampant in their own countries,” said Israel’s Foreign Ministry. “Anti-Israeli policies of the kind adopted today only serve to fuel that antisemitism.”
New Zealand imposed travel bans last week on three Israelis: Itamar Yehuda Levi, Harel David Libi and Eliav Libi. Foreign Minister Winston Peters said the bans were not aimed at the Israeli government or people, but targeted “three individuals who have actively worked to expand illegal settlements in the West Bank, including through violence.” Levi and his construction company, Eyal Hari Yehuda, were also listed as targets of new sanctions from the United Kingdom. Levi, Harel David Libi and Eliav Libi could not be reached for comment.
France on Tuesday joined a growing list of countries to ban Smotrich, Israel’s far-right finance minister who oversees demolition and construction in a portion of the West Bank. The ban comes days after Smotrich visited the United States to march in a pro-Israel parade in New York City, surprising many local Jewish leaders who said they do not support him.
Smotrich has already been barred from entering Ireland, Spain, the United Kingdom, Norway, Australia, New Zealand, the Netherlands and Slovenia. Smotrich did not respond to a request for comment.
Those countries have also previously banned Itamar Ben-Gvir, Israel’s far-right national security minister. France banned Ben-Gvir last month after he posted a video of himself taunting detained activists who attempted to carry aid to Gaza on a flotilla.
France added four leaders of settler organizations and 21 settlers accused of violence to its travel ban list on Tuesday, according to foreign affairs minister Jean-Noël Barrot.
The United Kingdom, for the first time, has explicitly advised businesses against economic and financial activity in the West Bank. The country released a list of seven sanctioned people and entities that financially support Israeli settler farms and outposts in the West Bank or are associated with physical attacks on Palestinians.
Foreign Secretary Yvette Cooper also announced at least £10 million for the Palestinian Authority, which runs Palestinian areas of the West Bank, and £1 million for humanitarian assistance with clearing mines in Gaza.
Canada announced that its measures on Tuesday brought the country to a total of 19 individuals and 12 entities sanctioned for “their role in extremist settler violence.”
The joint statement issued by five foreign ministers said that illegal settlements, which shrink the territory inhabited by Palestinians, undermine “viability of the State of Palestine and the prospects for peaceful coexistence.” Norway officially recognized a Palestinian state in May 2024, with France, the United Kingdom, Canada and Australia following suit in September 2025. New Zealand has not recognized a Palestinian state.

Colombian President Gustavo Petro sparks outcry over tweet reading ‘Heil Hitler’
(JTA) — Colombia’s outgoing president, Gustavo Petro, sparked fierce condemnation from Israeli and Latin American leaders after he tweeted the phrase “Heil Hitler” Sunday in response to an op-ed endorsing a candidate in the country’s upcoming presidential election.
Petro, a left-wing president in the final weeks of his term ahead of the country’s June 21 runoff election, posted the Nazi phrase in response to an op-ed supporting right-wing presidential candidate Abelardo de la Espriella.
Petro subsequently defended his use of the Nazi slogan, arguing that he was critiquing the language used by the op-ed’s author, which he said included “fascist phrases.”
His defense came after criticism from Israeli leaders and others who said the “Heil Hitler” comment was inappropriate.
Israel’s ambassador to the United Nations, Danny Danon, called on the Colombian leader to “come to your senses and apologize” before Wednesday, when he is slated to preside over a debate at the United Nations Security Council.
“President of Colombia, @petrogustavo, whatever is going on in your personal life, there are lines that must never be crossed,” Danon wrote in a post on X. “Using Nazi slogans is a disgraceful low from which there is no coming back.”
Israel’s Foreign Ministry also decried the post, writing on X that it was a “total loss of moral compass and an indelible stain on Colombia’s legacy.”
The episode comes amid shifting norms about the use of Holocaust analogies and language in political discourse. After being considered out of bounds for a long time, people on both the right and the left have increasingly shed those norms amid growing political polarization and extremism around the world.
The “Heil Hitler” post was not the first time Petro has landed in hot water for invoking the Holocaust. In the wake of Oct. 7, Petro drew backlash from Jewish and Israeli leaders for likening the actions of Israel to Nazi Germany. On social media, he has repeatedly called political rivals Nazis, including last month when he wrote in a post on X that Israel’s national security minister, Itamar Ben-Gvir, had behaved like a “true Nazi” after he posted videos taunting detained activists from a Gaza-bound aid flotilla.
In 2024, Petro also severed diplomatic ties with Israel, accusing the country of commiting genocide in Gaza, an accusation Israel has denied. Espriella, who was endorsed by President Donald Trump, has vowed to renew diplomatic ties with Israel.
On Monday, 24 Latin American lawmakers signed onto a statement condemning Petro’s rhetoric, warning that his repeated use of references to Naziism risked distorting Holocaust memory.
“The use of references to Nazism must not become a rhetorical tool to discredit political or ideological positions. Democratic leaders have a responsibility to promote a respectful public debate that is conscious of the weight of words,” the statement read.
The statement was initiated by the Coalition of Latin American Legislators Against Antisemitism, which is led by the Combat Antisemitism Movement. The signatories included lawmakers from Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Guatemala, Honduras, Mexico, Panama, Paraguay, Peru, the Dominican Republic and Uruguay.
Shay Salamon, CAM’s executive director of Latin American affairs, said in a statement that Petro’s invocation of the phrase reflected a “troubling record of antisemitic expressions and conduct” by the Colombian leader.
“When a leader uses the authority of his office to stigmatize the Jewish people or trivialize their historic suffering, silence is no longer an option,” Salamon said.
