There has been a serious and systemic failure to tackle antisemitism across the five biggest social media platforms, resulting in a “safe space for racists”, according to a new report.

Facebook, Twitter, Instagram, YouTube and TikTok failed to act on 84% of posts spreading anti-Jewish hatred and propaganda reported via the platforms’ official complaints system.

Researchers from the Center for Countering Digital Hate (CCDH), a UK/US non-profit organisation, flagged hundreds of antisemitic posts over a six-week period earlier this year. The posts, including Nazi, neo-Nazi and white supremacist content, received up to 7.3 million impressions.
