As antisemitic hatred surges across Europe’s digital spaces, more than 80 percent of reported anti-Jewish posts remain online, exposing major failures in platform enforcement as increasingly threatening rhetoric continues to spread across social media, according to a new study.

Conducted by the World Jewish Congress’s Technology and Human Rights Institute (TecHRI), which monitors online platforms and tracks antisemitic content, the study revealed significant gaps in social-media companies’ enforcement of hate-speech policies, allowing threatening and hateful content to remain online even after being reported.

Experts found that 81.2 percent of the 754 antisemitic posts reviewed between February 2025 and April 2026 were still online in May, with 613 posts remaining accessible despite being reported — a stark indication of how widely anti-Jewish hate continues to evade platform enforcement.

Social media companies need to step up their removal of antisemitic content on their platforms.

Among the most alarming findings was that explicit calls for violence against Jews continued to circulate online despite repeated reports and clear evidence, including ISIS propaganda urging attacks on synagogues and Jewish neighborhoods in the United States and Europe.

As social-media companies continue to fall short in enforcing their policies, the report found that Israel-related antisemitism had the lowest removal rate, with just 5.2 percent of such posts taken down, while posts equating Israeli policies with Nazi Germany almost always remained online.

TecHRI executive director Yfat Barak-Cheney warned that social-media companies’ failure to consistently enforce their own rules is allowing antisemitic hatred to spread largely unchecked online, deepening an increasingly hostile climate and raising serious concerns for Jewish communities.

“Jewish individuals and institutions are the target of hate-fueled violence at a higher rate than any other religious or ethnic group. These acts are then glorified and promoted across social media platforms,” Barak-Cheney said in a statement.

“It is up to companies to enforce their policies and remove content when it violates existing standards designed to protect vulnerable communities,” she continued.

According to WJC data, reporting antisemitic content had little impact on whether it was removed, with platforms taking down just 19.5 percent of formally reported posts compared with 18.2 percent of posts that had not been reported.

Among the platforms examined, TikTok recorded a 64 percent removal rate, far outpacing the other major social-media companies, none of which removed more than 15 percent of the antisemitic posts reviewed.

Facebook recorded the highest rate of user reporting, with 76 percent of posts flagged, yet only 13.9 percent were ultimately removed, placing it among the platforms with the weakest removal rates.

In light of these findings, the WJC urged tougher action from social-media companies and greater transparency over how reported antisemitic content is handled, while calling on European regulators to use the Digital Services Act to hold platforms accountable.
