Twitter’s policies of banning and suspension are under fire again, this time from former Trump campaign adviser Roger Stone, whose account was suspended, seemingly indefinitely, after he tweeted a storm of obscenities at a number of CNN anchors on Saturday night.

“This is a strange way to do business and part and parcel of the systematic effort by the tech left to censor and silence conservative voices,” Stone said on Sunday in an e-mail to Politico, warning that “the battle against free speech has just begun” and saying he planned to take legal action against Twitter. According to Politico, Stone had gone after a number of CNN’s staff in a series of tweets, seemingly in response to a report that an indictment from Robert Mueller’s Russia investigation was imminent. Stone tweeted that anchor Don Lemon was “dumber than dog shit” and deserved to be mocked.

To Stone, what he said to earn suspension is no different from average trolling on the platform. “I have been inundated on Twitter with death threats, threats to kill my wife, my family, my children and even my dogs yet Twitter seems unconcerned with these bloggers,” Stone said. Responding to reports that his account was banned for good, Stone also said that he was told by Twitter that his suspension was supposed to last “three hours and 22 minutes,” but the account has been dark all night and at time of publication, is still suspended.

On Friday, Twitter announced that it would begin enforcing its new, stricter anti-harassment policies in November. C.E.O. Jack Dorsey announced earlier this month that the social media platform would be cracking down on users’ behavior to curb the spread of “hate symbols,” “violent groups,” and “unwanted sexual advances.” In lieu of a comment on Stone’s suspension, a Twitter representative pointed BuzzFeed reporters to the new policy on abusive behavior.
