Pro-gamer Tyler "Ninja" Blevins posted a video on Sunday admonishing streaming platform Twitch for using his now inactive channel to promote other streamers, including a porn account.
Ninja is best known for streaming "Fortnite," and left Twitch earlier this month to enter into an exclusive partnership with Mixer, Microsoft's new streaming service.

In the video, Ninja said that the transition from Twitch to Mixer had been relatively painless. However, Ninja said he discovered Twitch had been using his inactive channel to advertise other streamers to the 14.5 million followers he amassed.
"They don't do this for anyone else who is offline by the way, just me," he said. Ninja specifically took issue with a porn account which he said was "number one being recommended" on his channel.
"I have no say in any of this stuff," he said, later adding: "For anyone who saw that, for anyone whose kids â or who just didn't obviously wanna see that â I apologise and I'm sorry."

Twitch CEO Emmett Shear tweeted later that day that the platform has been "experimenting with showing recommended content," but added that the "lewd" account Ninja mentioned violated terms of service and was permanently suspended.
He added that the "recommended content" had been suspended on Ninja's channel pending an investigation into how the porn account ended up there. He apologized directly to Ninja. "It wasn't our intent, but it should not have happened. No excuses," he wrote.
Twitch was not immediately available for comment on Ninja's comments when contacted by Business Insider.
