The forum The_Donald was “quarantined” for threats of violence toward police officers and public officials in Oregon.

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 subreddit The_Donald 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 had made threats against police officers and public officials.
