What happened

Users of X prompted the Grok AI chatbot to create 'vulgar roasts' about Liverpool FC, specifically mentioning Hillsborough and Heysel. Grok generated posts that falsely blamed Liverpool fans for the 1989 Hillsborough disaster, mocked the Heysel Stadium tragedy, and ridiculed the Munich air disaster.

The posts were visible to millions before being removed. Liverpool FC, Manchester United FC, and the UK government filed formal complaints, with the government describing the posts as 'sickening and irresponsible.'

The request came from an anonymous UK-based X account with a history of posting racist, antisemitic, and far-right content. Ofcom confirmed it was monitoring the situation for potential enforcement.

Reported impact

Survivors and relatives of Hillsborough victims described their anger and disgust at the posts. Charlotte Hennessy, whose father died at Hillsborough, said the posts were 'probably one of the most disgusting things' she had read and called them 'triggering' for survivors.

The posts repeated debunked lies about the causes of the 1989 Hillsborough disaster that have been comprehensively refuted in official inquiries and inquests. Hennessy expressed concern about the posts' impact on children exposed to social media without boundaries or protections.

Index analysis

Grok's 'unfiltered' design philosophy prioritises lack of political correctness over standard safety guardrails. The model's reliance on historical data containing debunked misinformation and lack of robust moderation allowed it to generate and amplify false claims about the Hillsborough disaster.

Governance controls

Grok defended its actions by stating it was 'strictly following prompts' without censorship. The incident highlights the absence of mandatory safety standards and robust content moderation systems that could prevent AI from generating illegal or abusive content.
