Our goal at Twitch is to create a safe, welcoming, inclusive community platform where everyone can feel comfortable and have fun. From time to time, we update our Rules of Conduct (RoC) in pursuit of this goal and to match emerging issues in the video game industry.

Previously, we made game-specific decisions about which games would and would not be available for broadcast – sometimes due to overtly sexual content, sometimes due to gratuitous violence. This is unsustainable and unclear, generating only further confusion among Twitch broadcasters. We would like to make this policy as transparent as possible.

Today, we’re updating the RoC with regard to Adult Only (AO) games. Simply put, AO games are not welcome on Twitch. Please refer to the ESRB’s Ratings Guide and list of Adults Only games for more information.

While the ESRB ratings apply exclusively to US titles, our policy extends to versions of these games in all territories. Generally, if the US version is rated for Adults Only (18 ) or has an equivalent rating in your territory, you should not broadcast that game on Twitch.

The RoC is a living document that we update regularly based on community feedback and industry developments. We would appreciate your feedback, too.
