Mitchell announced his ban in a post on Parler on Friday, laying his Twitter handle to rest after accumulating more than 600,000 followers. Earning regular retweets from President Donald Trump, the account was a source of controversy, at times backing ‘QAnon’ conspiracy theories and voicing skepticism toward Covid-19, among other things.

“Twitter just suspended me for opposing masks. Who knows if I’ll ever be back,” Mitchell wrote, adding sarcastically “I’m sure their decision wasn’t political at all.”

While he did not elaborate further on the ban, Mitchell was reportedly first handed a 7-day suspension for a mask-related post, which is believed to have been made permanent after he posted from a secondary account for his media company, YourVoice America. A Twitter spokesperson told Daily Beast political reporter Will Sommer that Mitchell had violated the platform’s rule on “ban evasion,” which bars users from tweeting from alternative accounts once handed a suspension or ban.
