Twitch’s oft-vocal chief executive officer, Dan Clancy, has claimed the reason why the algorithm is unable to pick up on all the sexual content on the streaming platform—and therefore ban it—is because the creators aren’t using the correct labeling.

The CEO’s declaration came after he appeared on Spanish Twitch star Rubius’ stream earlier this month. During the stream, he was showing off new Twitch features when his screen accidentally popped up with not-so-savory content. He laughed it off, before later explaining he’s had to manually find “offending clips” because the system hasn’t been pinging them—which has led to his algorithm offering up those kinds of suggestions.
