This is overblown. It's no worse than radio shows teens used to listen to. Idiots would call in and say all sorts of crap. Twitch viewership is young so there's a lot of "edgey" channels.

There's tons of streamers that don't allow their chat to be a disaster. For others, allowing chat to go nuts is their MO.

The funniest thing to me is utterly un-insteresting "tit streamers" wearing as little as they can to avoid violating ToS.

IMO twitch is just a reflection of the differences in viewing tastes. There's an extremely wide range of channels and personalities. Something for everyone.
