Reddit Bans r/Incels (2017) and Successor r/Braincels (2019)

In October 2017 Reddit updated its content policy to prohibit content that 'encourages, glorifies, incites or calls for violence or physical harm against an individual or group of people.' On November 7, 2017, the company applied that rule to r/Incels, a roughly 40,000-subscriber forum for self-described 'involuntary celibates.' While nominally a support space, the subreddit had become a hub for misogynistic 'black pill' ideology, with posts that condoned or advocated rape and violence against women and glorified mass shooter Elliot Rodger.

The ban relocated rather than dispersed the community. r/Braincels was created as a near-identical successor and quickly became the most popular incel subreddit, growing into the tens of thousands of subscribers. After the April 2018 Toronto van attack, some users praised perpetrator Alek Minassian before moderators deleted some posts.

Reddit took graduated action against r/Braincels: administrators quarantined it on September 28, 2018, citing 'the high degree of misogyny present in this subreddit,' then banned it in late September/October 2019 for violating the policy against content that harasses or bullies. After each removal, incel discussion migrated further from Reddit's reach — first to the successor subreddit, then to dedicated standalone forums such as incels.co, beyond the platform's enforcement entirely.

The episode sits within the documented link between online incel communities and real-world violence, including Elliot Rodger's 2014 Isla Vista killings and Alek Minassian's 2018 Toronto van attack, both of which incel forums repeatedly referenced. Researchers studying Reddit's quarantine and ban interventions have used r/Braincels as a key case, generally finding that gating or removing a community reduces its on-platform activity but does little to dissolve the underlying ideology, which simply migrates to less-moderated venues.
