Twitch recently updated their Code of Conduct to clarify their decency rules more.
The new policy requires streamers to dress appropriately with no "sexually aggressive clothing – including lingerie, swimsuits, pasties, and undergarments." This also includes no showing of the mid-section either. This rule applies to both males and females and has nothing to do with the Amazon buyout.
This is a long-standing policy meant to create an open, supportive, safe environment for all gamers, We are not the fashion police and this is not a new policy, just clarity on a long-standing one rooted in common sense. In other words, don't broadcast naked or in lingerie, swimsuits, pasties and undergarments. We don't actually get many cases of dress code violations, but felt it should be clarified since our community has occasionally asked about specifics. Twitch PR Director Chase
The people at Twitch don't actually monitor all streams, so it will be up to the community to report people who break the rules.
