Distorting the Truth: How Antisemitism Was Amplified Online After the Boulder Attack

A new report analyzing online responses to the Boulder terrorist firebomb attack on June 1 exposed a deeply troubling pattern — the rapid and coordinated spread of antisemitic rhetoric, disinformation, and conspiracy theories across X, Facebook, and TikTok.

The report — commissioned by CAM and conducted by the Cyabra social media analytics — looked at social media discourse on the attack from June 2-4. It found that antisemitic narratives were deliberately amplified — not only by known extremists, but also by networks of inauthentic accounts, designed to distort the facts, inflame tensions, and manipulate public perception.

Key findings included:

— 10,113 unique profiles generated more than 14,000 posts and comments related to the Boulder attack.

— A significant portion of this content glorified antisemitic violence and framed the attack as legitimate or heroic.

— 1,379 posts promoted classic antisemitic conspiracies, denying the facts of the attack and delegitimizing Jewish victimhood.

— 22% of the accounts were determined to be inauthentic — yet they disproportionately shaped the conversation, receiving more than 3 million views.

— Prominent antisemitic influencers acted as central amplifiers, spreading hate with the assistance of these fake networks.

This report provides an alarming window into how antisemitism is rapidly deployed and amplified in the digital space following acts of violence — and why confronting it is critical for ensuring truth, accountability, and safety for Jewish communities.
