Why do you think those site are for +18 and are tagged porn/eroctic sites that provide those services ?
Twich is a gaming site not a site where people sell themselve as a sexual attraction object who offer special services.
I'm pretty sure you can be sexy and not actually "sell" yourself. Also if they aren't actually advertising for sexual acts or favors, why is it a problem?
We use attractiveness and sexiness to make plenty of things more engaging and entertaining, not just for sex.
Topless and nude streamers should be gotten rid of, yes. Sexy, skimpy, sexualized streamers not so much unless they are going down a path that encourages sexual acts outside of the service.
It's Twitch's bar to set what the feel is proper or not, but I think they went a little overboard here.
I don't like or watch those streamers that purposefully dress themselves down for viewers, but I have no issue with them. If they're playing video games, engaging with the chat, and everyone is having a good time, what's the problem? If advertising in an issue, give them an 18+ (or even 21+) filter and don't partner them.
It's whatever though. I just hope this ultimately generates other avenues of streaming games, not just Twitch.
I was checking out CS:GO streams last night and the biggest stream was this girl who wasn't even playing the game, she was having a Q&A session
How long were you watching her stream though? It's very common for streamers to do Q&A session between gameplay sessions or before the end of their stream. Some popular streamers even dedicate a day to it.
