Audit: Most Antisemitic Content Flagged by EU Jews Remains Online

A new audit by the World Jewish Congress (WJC) reveals a significant failure by major social media platforms to address antisemitic content reported by users. The study, titled “Flagged and Failed: Platform Responses to Antisemitic Content Reported by Jewish Communities,” found that a staggering 81.3% of reported antisemitic posts remained publicly accessible online.

The audit analyzed 754 reports submitted by European Jewish community members between February 2025 and April 2026. These reports, categorized using the International Holocaust Remembrance Alliance’s working definition of antisemitism, spanned six prominent social media platforms. A crucial finding was that the act of formally flagging content through a platform’s built-in reporting mechanism had virtually no impact on its removal.

Data collected throughout May 2026 showed that 613 out of 754 reported antisemitic posts were still live. The removal rate for content formally flagged by users was approximately 19%, only marginally higher than the roughly 18% removal rate for content that was never flagged. This suggests a systemic issue with platform moderation and accountability.

The analysis highlighted disparities across platforms, with Facebook receiving the highest volume of reports at 34.4%, followed closely by Instagram and X/Twitter at 26% each. The WJC's findings underscore the ongoing pressure platforms face to improve their policies and enforcement against online hate speech, particularly concerning antisemitism, which encompasses traditional tropes, Holocaust distortion, incitement to violence, and hostility related to Israel.
