The most popular YouTuber is back on Twitter after joking that his account became unverified because he joined Islamic State.

Felix “PewDiePie” Kjellberg’s account was briefly suspended this week and the blue tick denoting his verified status was removed after he changed his avatar to an image that could be interpreted as obscene.

Kjellberg tweeted on Tuesday that he was unverified because he and a friend joined IS. The next day, he explained on YouTube that he purposely unverified his account “as a joke” and because he believes the system is annoying.

The popular internet personality has more than 47 million YouTube subscribers and seven million Twitter followers.

A spokesman for Twitter declined to comment.
