Reddit is one of the largest social networks in the world, built around image sharing and threaded discussions.
Usually those who claim to hate Reddit the most are the one that use it the most. It has a reputation of being very SJW.
There have been a number of incel boards on Reddit:
- /r/BlackPillScience (not entirely incel though)
Banned or deleted
- r/Pirateparadise (another braincels ban evasion)
