What happened
In mid-December 2024, Reddit moved to restrict content related to Luigi Mangione, the man charged in the killing of UnitedHealthcare CEO Brian Thompson, after parts of his writings circulated online. The platform began removing links to the manifesto, which journalist Ken Klippenstein had published in full on his Substack, with some takedowns carried out by individual subreddit moderators and others by Reddit staff; the site also began automatically blocking posts attempting to link to the document. Reddit said 'manifestos related to violent acts' violate its policy against content that encourages or glorifies violence, while noting users could still discuss the case and news coverage of it.
The enforcement targeted communities and posts that had sprung up around Mangione, who had become a folk-hero figure in some online corners. The crackdown drew significant backlash from users who accused Reddit of censorship and inconsistent moderation. The episode highlighted the tension between Reddit's stated rules against violent content and its community-driven culture, and it became a flashpoint in the wider debate over how platforms should handle content tied to a polarizing, high-profile crime.
