Twitch said that, starting next month, it will ban the streaming of certain gambling websites that aren’t licensed in the U.S. or “other jurisdictions that provide sufficient consumer protection.”

The move by the Amazon-owned livestreaming platform, most popular among game creators, comes after reports that a streamer called ItsSliker had scammed fellow Twitch creators out of hundreds of thousands of dollars to support a “gambling addiction,” as The Verge reported.

In a tweet Tuesday, Twitch announced that as of Oct. 18, it will ban livestreaming sites that provide dice games, slots and roulette. It identified four sites that will be banned — Stake.com, Rollbit.com, Duelbits.com and Roobet.com — and said “we may identify others as we move forward.”
