Primary record Reddit's content policy captured on 11 September 2015 lists quarantining and banning of communities among its enforcement options and states that Reddit does not prescribe moderators' use of its tools, and on 29 June 2020 Reddit announced that it was banning about 2,000 subreddits, including r/The_Donald and r/ChapoTrapHouse.
