Reddit limited access to a forum popular with supporters of President Trump on Wednesday, saying that its users had violated rules prohibiting content that incites violence.
Visitors to the The_Donald subreddit were greeted Wednesday with a warning that the section had been “quarantined” and asking if they still wanted to enter.
Site administrators said that users of the online community, which has about 750,0000 members, had made threats against police officers and public officials.
