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.

Boulder hostage-march firebombing suspect to plead guilty to state charges
(JTA) — The man charged with firebombing a Boulder, Colorado, march for Israeli hostages in 2025 will plead guilty to killing one person and attempting to kill others in the incident, according to documents filed in the case over the weekend.
Mohamed Sabry Soliman, who was arrested at the scene of the June 1, 2025, attack, is asking for his ex-wife and children to be able to remain in the United States as a condition of his guilty plea, according to the documents.
His ex-wife and five children, like him all Egyptian nationals who came to the United States in 2022 via Kuwait, were arrested by immigration authorities shortly after the attack. They were detained until Thursday, when they were released from a detention center in Texas, then briefly detained again on Saturday in Boulder and, their attorneys say, put onto a plane bound for Egypt before being freed once again. His ex-wife, whom he divorced in April, has not been charged with a crime and said she did not know about Soliman’s planned attack.
Soliman is reportedly pleading guilty to all state charges but still faces federal charges in relation to the attack, which he allegedly said he staged to “wanted to kill all Zionist people and wished they were all dead,” according to an earlier court filing. He has previously pleaded not guilty to the federal charges, for which prosecutors could seek the death penalty.
Thirteen people were physically injured in the attack, which took place on a pedestrian mall in downtown Boulder where supporters of the Israelis then held hostage in Gaza marched weekly. One, 82-year-old Karen Diamond, died weeks later of her injuries.

Her body has been unidentified for decades. Her Ashkenazi DNA may explain why
Murder investigators in Arizona are encountering a stubborn obstacle to solving a decades-old cold case involving an unidentified dead body: The woman’s Ashkenazi Jewish DNA.
In 1989, an unclothed dead body was found on the side of a highway in northwest Arizona. The woman was never identified, though small details offered clues about her life: red nail polish on her fingers and toes, faux diamond stud earrings, and a handmade floral blouse found under a nearby tree.
The woman appeared to have been beaten, found with a broken nose and possible hematoma on the left side of her skull, though the medical examiner did not determine a cause of death. An autopsy determined the woman was between 25 and 30 years old.
In 2021, authorities reopened the case and uploaded the woman’s DNA profile to genetic databases available to law enforcement, hoping for a breakthrough. Instead, they hit a wall.
“Investigators learned that the victim was 96% Ashkenazi Jew, which made it extremely difficult to trace her ancestry and locate family members,” the Mohave County Sheriff’s Office said in a statement.
Ashkenazi Jews who try to track down relatives through genetic testing are familiar with the problem that the sheriff encountered: DNA testing, usually a powerful tool for finding relatives, often does not yield usable results for them.
Adina Newman, a professional genealogist and co-founder of the Holocaust Reunion Project, which uses DNA testing to help connect Holocaust survivors and their relatives to lost family, says two factors explain why genetic testing has limited use for many Jews. One is what’s known as the founder effect, when a population can be traced back to a small number of ancestors — as few as 350 people in Ashkenazi Jews’ case. The other is endogamy, the practice of marrying within a community over many generations.
As a result, a person with 100% Ashkenazi DNA can have more than 200,000 DNA matches in popular genetic databases, according to Newman. From such a large pool, it can be difficult to pinpoint close relatives.
“Ashkenazi Jews are all DNA cousins. But am I going to find it meaningful in a [family] tree?” Newman said. “Mostly no. We’ve just kind of accepted that it convolutes things.”
Investigators, however, aren’t giving up. The Mohave County Sheriff’s Office enlisted the help of the Investigative Genetic Genealogy Center at Ramapo College in New Jersey, which last week released an artistic rendering of what the woman may have looked like based on her remains.
“This doesn’t mean that cases of Ashkenazi Jews are impossible to solve,” David Gurney, director of the Investigative Genetic Genealogy Center, told the Forward. “It just is going to take a lot more effort.”
Jewish Jane Does
The 1989 case in Arizona is not the only time Ashkenazi DNA has posed a challenge in identifying remains. Another active case, an Ashkenazi Jewish woman whose dead body was found in 1981 in Olympia, Washington, remains unsolved.
Other cases have taken years to crack. In 2024, investigators working with the DNA Doe Project finally identified the body of a Jewish woman found murdered in a California vineyard in 2011 as Ada Beth Kaplan. It also took more than a decade to identify Mitchell Mendelson, a Jewish man whose body was found in a wooded area near his home in Lancaster, Pennsylvania in 2012.
In both cases, the deceased’s Ashkenazi DNA made the process more laborious for investigators, though DNA also eventually led investigators to be able to make the identifications.
To be sure, Ashkenazi Jews are not the only population that exhibits endogamy, which is also common among Pennsylvania Dutch communities, Icelanders, French Canadians and other tight-knit societies.
But the combination of Ashkenazi Jews’ genetic overlap and a complex historical record can make Jewish identification especially difficult cases to crack, Newman said.
For instance, in Newman’s own family, records changed from listing Vilna as being located in Russia, then Poland, then Belarus over a short period of time. But her family members hadn’t moved; the borders were changing around them. Last names in her family were also altered to sound more anglicized.
“You have to know these things. And it’s hard because a lot of genetic genealogists, even the best ones, are not familiar with that,” Newman said, “They need people who understand the Jewish genealogy aspect.”
Even when genealogists have such expertise, limited data can slow progress. Lingering trauma from the Holocaust has made some Jews hesitant to upload their DNA to public databases, Newman said.
Others have privacy concerns: In 2024, 23andMe settled a class-action lawsuit for $30 million in which customers accused the company of failing to notify customers with Ashkenazi Jewish heritage that they appeared to have been specifically targeted by hackers, who sold their information on the dark web.
Yet unless they have a search warrant, law enforcement agencies are constrained to cross-referencing DNA profiles with just two databases: GEDmatch and FamilyTreeDNA, which collectively host about 3 million profiles. By contrast, Ancestry.com has more than 29 million DNA profiles, according to its website, and 23andMe has roughly 15 million.
Ancestry.com and 23andMe users who wish to make their profile visible to researchers can upload their information to GEDMatch or FamilyTreeDNA for free.
“We always depend on members of the public taking consumer genetic genealogy tests to solve any case,” Gurney said. “That’s even more important in cases of endogamy here.”
Those challenges compelled Rabbi Mendel Super, who leads Chabad of Lake Havasu City in Mojave County, Arizona — about an hour’s drive away from where the woman’s body was found in 1989 — to spread the word about the case in the Jewish community. After Super learned of the woman’s Jewish ancestry, he contacted the local sheriff’s department to offer his help.
He’s since connected authorities with experts in Jewish genealogy and is publicizing the case on social media, hoping his Jewish network can help identify a relative.
“There’s millions of people who it could be, but there’s only a few million Jews in the world, and fewer in this country,” Super told the Forward. “So I think there’s got to be someone who knows something.”
Newman, too, sees broader participation as key. She encourages Jews to share their DNA profiles, noting that researchers view far less information than many expect — just the amount of shared DNA needed to construct family trees, not a complete genetic profile. People can even upload DNA profiles anonymously, she said, giving researchers the option to contact them only if there’s a notable match.
“These people deserve dignity, to have their names,” Newman said. “It could really be you, especially in the Jewish community. You could be the one that helps solve the case and gives us her name back.”

Israeli Restaurant Owned by Syrian Repeatedly Attacked in Germany
Illustrative: 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.

An Israeli restaurant in Germany has been repeatedly attacked while its Syrian Kurdish owner has been subjected to relentless harassment, underscoring a broader climate of hostility faced by Jews and Israelis across the country.
Restaurant owner Billal Aloge, a Muslim from Syria, has been subjected to escalating hatred and violence after publicly expressing support for Jewish life in his city by opening restaurants aimed at fostering dialogue and coexistence.
Shortly after opening his Israeli restaurant “Jaffa” in Freiburg, a city in western Germany, Aloge faced immediate hostility and a wave of online abuse.
Even after filing multiple police reports, the harassment did not stop, with unknown individuals continuing to target the restaurant. This included incidents of vandalism such as throwing rotten eggs at the premises, prompting the owner to repeatedly seek police intervention.
Then last Tuesday, the restaurant’s newly deployed food truck was vandalized after being parked for just a single day in Colombipark in the heart of the university town, according to German media.
The food truck was extensively damagd, with paint thrown across its exterior, Israeli symbols defaced with Palestinian flag stickers and antisemitic slogans, and its door kicked so forcefully that it was left visibly dented.
Three days later, Aloge and his wife were preparing to open the food truck for Labor Day, when they discovered a broken side mirror.
“The food truck was brand new. I bought it for the new season and had it lovingly refurbished,” Aloge told the German newspaper Bild.
“Once again, I had to file a police report and now I estimate the total damage from the two attacks at approximately 30,000 euros,” he continued.
Freiburg Mayor Martin Horn strongly condemned the attacks, stressing that the city would not tolerate such acts of hatred and would take them seriously, with full efforts to ensure accountability and protection for those targeted.
“There is no place in Freiburg for antisemitism, anti-Muslim racism, or any other form of hatred and incitement,” the German official said in a statement.
Like most countries across Europe and the broader Western world, Germany has seen a shocking rise in antisemitic incidents over the last two years, in the wake of the Hamas-led invasion of and massacre across southern Israel on Oct. 7, 2023.
According to recently released figures, the number of antisemitic offenses in the capital city Berlin reached a record high in 2025, totaling 2,267 incidents, including violence, incitement, property damage, and propaganda offenses.
By comparison, officially recorded antisemitic crimes were significantly lower at 1,825 in 2024, 900 in 2023, and fewer than 500 in 2022, prior to the Oct. 7 atrocities.
Officials warn that the real number of antisemitic crimes is likely much higher, as many incidents go unreported.
In one of the latest antisemitic incidents in the country, a synagogue in Cottbus, a city in eastern Germany, was defaced with a swastika painted on its facade, marking the second time in just four days that the Jewish house of worship had been vandalized.
Separately, authorities also discovered antisemitic graffiti across several apartment buildings in Berlin-Pankow, including messages reading “Kill all Jews,” a swastika, and the statement “Only a dead Jew is a good Jew,” in a series of disturbing incidents over the week.
