New CCDH Research Finds X Hosted Flood of Antisemitic Hate, Calls for Further Violence and Conspiracies Following Golders Green Attack

London, 15th May 2026 — In the aftermath of the attacks in Golders Green on 29 April, X once again became a whirlpool of antisemitic abuse. New research published today by the Center for Countering Digital Hate (CCDH) reveals calls for further violence and conspiracy theories targeting the Jewish community.

CCDH researchers found that antisemitic abuse inundated prominent British Jewish figures and organisations — including Chief Rabbi, Sir Ephraim Mirvis — who posted messages of grief and solidarity following the Golders Green attack. The posts included celebrations of violence against Jews, harmful antisemitic tropes and expressions of desire for further attacks.

Researchers downloaded all replies posted in response to ten prominent Jewish accounts who had expressed grief or concern about the attack. From these, they identified 130 hateful ones which remained live on X at the time of analysis, despite appearing to breach the platform’s own policies on hateful conduct and violent speech.

Examples included:

• “Less Jews in the world, the better!”
• “This is the treatment Jews really deserve.”
• “Too bad he didn’t get more.”

CCDH also analysed the 100 most-viewed posts containing conspiracies that the attack was a “false flag” orchestrated by Israel, Mossad, or Jews themselves. Collectively, these posts accrued more than 250,000 views. None of the posts carried Community Notes fact-checks, despite Elon Musk previously claiming that the system could rapidly correct harmful falsehoods such as Holocaust denial.

These findings come as Ofcom, the UK’s online safety regulator, announces that X has committed to introducing stronger protections and improved response targets for illegal hate and terror content under Ofcom’s ongoing compliance programme. This announcement follows sustained campaigning by CCDH in the wake of last year’s Heaton Park Synagogue attack. However, the findings today underline the urgent need for this compliance programme to succeed.

Imran Ahmed, CEO of the Center for Countering Digital Hate, said: “This new research shows how, even in a moment of immense pain and fear for the Jewish community, expressions of grief and solidarity were met on X with celebrations of violence, antisemitic tropes and calls for further attacks. Yet the platform did little to tackle it.

We welcome this announcement from Ofcom, but the stakes here are far too high for failure. Online abuse does not exist in isolation. It has real-world consequences for people who are being intimidated and endangered simply because of their faith. Ofcom now has an opportunity to prove that the Online Safety Act can deliver meaningful accountability. We will be watching closely to ensure this results in meaningful action, not just words.”

Sir Ephraim Mirvis KBE, Chief Rabbi, said: “The horrifying tidal wave of anti-Jewish invective on social media, and particularly on X, contributes directly to acts of abuse and violence on our streets, because when platforms fail to act, they create a permissive environment in which hatred flourishes. Unfortunately, meaningful action to tackle this problem is long overdue and the consequences are being deeply felt.”

Danny Stone MBE, Chief Executive of the Antisemitism Policy Trust, said: “CCDH has exposed that X continues to fail its users, with the platform hosting antisemitic conspiracies, hatred and even calls for violence without consequence. For many Jewish public figures in Britain, simply expressing support for the victims of violence now triggers coordinated antisemitic abuse. This cannot become normalised. Ofcom has both the responsibility and the regulatory powers under the Online Safety Act to ensure that platforms like X cannot continue to allow antisemitic hatred and incitement to flourish unchecked, and I look forward to it exercising those powers to the fullest extent possible.”
