Ninja has beef with Twitch,?? ?????? ??????? ???????? ??? ????? the platform where he first found fame.

The superstar streamer whose real name is Richard Tyler Blevins now reps Microsoft's competing Mixer, as of Aug. 1. But he left behind a community of 14.7 million followers on Twitch, and now he's claiming Twitch is exploiting the community he built without his permission.

Blevins laid it all out in a video posted to Twitter on Sunday. He starts by explaining his new streaming situation on Mixer and describes what he says was a "smooth" transition off of Twitch. "Super professional, we haven't said anything bad or negative about Twitch, obviously, because we haven't needed to."

But, he continues, in the days since Blevins left the platform, he and his team have noticed something odd about his dormant account. All 14.7 million followers are still there, but the main page where you'd normally find his stream carries the message "The streamer you're looking for is in another castle." Below that message is a list of other recommended channels.

"They don't do this for anyone else that's offline, by the way, just me," Blevins said. "And there are also other streamers who have signed with other platforms whose stream and channel remains the same. You can still see their [archived streams], they don't promote other streams, they don't promote other popular channels. But they do on mine."

(This is true for at least one former streamer, Renée, who left Twitch for Mixer in 2018. If you look at Renée's Twitch page now, it might be hosting another streamer but there's no "another castle" message or other channel recommendations. Both Renée's and Blevins' archived streams are still available.)

In the hours after Blevins posted his video, Twitch CEO Emmett Shear took to Twitter with a threaded apology, and an explanation for site turning the streamer's dormant account page into a promotional platform for other channels. Shear didn't address why Blevins page appears to be the only one that's been co-opted for Twitch's own promotional use, though he did say that those recommendations have been "suspended while we investigated how [pornographic] content came to be promoted."

Various forms of sexual content, including pornography, aren't permitted on Twitch streams, according to the site's rules.

Blevins' video continued: "I've been streaming for eight years. To build my brand, to build that channel. Fourteen and a half million follows." The real issue for him, though, is exactly what he said Twitch has been promoting.

"There was a porn account that was #1 being recommended on my channel. And I have no say in any of this stuff," Blevins said.

"So this is the line, this is the straw. We're trying to get the whole channel taken down to begin with, or at least not promote other streamers and other channels on my brand, on my freaking profile. So for anyone who saw that, for anyone whose kids just didn't want to see that, I apologize."

While the specifics of how pornographic content ended up on a Twitch channel promoted on Blevins' account aren't clear, streamers have found ways of circumventing the site's content policies over the years. In this case, it's likely that someone used their Fortnite-labeled stream -- that's what Blevins' page was used to promote, since that's his game -- to broadcast content that ran afoul of Twitch's rules. Because of the way streams are moderated, these breaches sometimes slip through.

In this particular case, the rule-breaking stream got to be so popular that it received prominent placement among the recommendations on Blevins' page.

Even with the porn issue having been addressed directly, Blevins has legitimate beef here. Even if Twitch terms of service somehow allow the company to commandeer the account page of a streamer who has moved on to another platform -- and that's not clear at this point -- this whole situation is an exceedingly bad look. Blevins page appears to be the only one that's been turned into a Twitch promotional platform, and Blevins has every right to ask why.
