Steam gambling sites such as GSGO Lotto and SteamLoto are no longer welcome on Twitch. The news comes after Valve made their stance on the sites clear and would be serving notices to cease operations through Steam to those sites.
The news comes in the form of a new blog post updating the Twitch and third-party terms of service and user agreements.
As a reminder, per Twitch’s Terms of Service, broadcasters are not permitted to stream content that breaks the terms of service or user agreements of third-parties. As such, content in which the broadcaster uses or promotes services that violate Valve’s stated restrictions is prohibited on Twitch. Our Rules of Conduct lists other examples such as playing pirated games and playing on unauthorized private servers.
So broadcasting the use of the Steam gambling sites will break the new terms of service and user agreements and could affect your future streaming options.
