Twitter suspended the accounts of upstart rival service Mastodon and several prominent journalists covering the social network’s billionaire owner Elon Musk.

Late Thursday, reporters from publications including the Washington Post, the New York Times, Mashable and CNN were listed as blocked and their tweets were no longer visible. Musk said the suspended profiles, which included sports and political commentator Keith Olbermann, were of people who had posted his real-time location, describing the information as "basically assassination coordinates.”

"I was given no warning. I have no email or communication from the company about the reason for suspension,” New York Times reporter Ryan Mac tweeted from a new account. He posted a screen grab from the app saying he’s been permanently suspended. "I report on Twitter, Elon Musk and his companies. And I will continue to do so.”
