Twitter CEO Jack Dorsey’s account sent a series of incendiary tweets on Friday after his account was compromised.
Dorsey’s account tweeted out “#nigger” and “Hitler is innocent,” among other inflammatory remarks. Another tweet read, “Intel is there’s a bomb at Twitter HQ.”
Some tweets were up for half an hour, though all were eventually deleted. Within the first few minutes of the inappropriate tweet spree, they had garnered thousands of likes and retweets.
“Yes, Jack’s account was compromised. We’re working on it and investigating what happened,” said a Twitter spokesperson shortly after the tweets were posted.
A bit more than an hour later, Twitter said Dorsey’s account was “now secure” and that there was “no indication that Twitter’s systems have been compromised.”
Later on Friday, Twitter said that the phone number associated with Dorsey’s account had been compromised because of a “security oversight” by the mobile phone company, which had allowed someone to send out tweets by text message from the number.
Some of the tweets from Dorsey’s account after it was compromised included the hashtags “#ChucklingSquad” and “#ChucklingHella.” When the U.K.’s Metropolitan Police Department was hacked last month ― and had inappropriate tweets, including “Fuck the police,” posted from its account ― the same “#ChucklingHella” hashtag was used.
Dorsey has come under fire in recent years for Twitter’s response to hate speech, harassment and extremist views propagated on the platform. The company was criticized last year for how long it took to ban notorious right-wing conspiracy theorist Alex Jones from the platform.
