Twitch bans streaming of adults only rated games

"Twitch bans streaming of Hatred" is pretty much the title here.

Hatred even rated by the American rating system? Usually indie games never go through any sort of classification before being publish.

They also banned Senran Kagura, and I didn't think they ever allowed AO games.

Well they eventually unbanned Senran under the condition that the stream doesn't focus on any sexual content lol.
