They aren't banning anything. They're changing the way tags work, hopefully, because they fucked up huge earlier this year and took away tags that people were using to identify themselves. They're also taking a tougher stance on sexual harassment, which is a good thing. They should have done it years ago. I mod in a few streams and the drooling shitlords we have to ban just make me shake my head. No, the female streamers aren't gonna fuck you. Go away.
The town hall was shit. DMCA explanations were complete and utter bullshit for those of us that stream music, and I don't mean in the background. I will probably wake up someday soon to a DMCA strike and/or a ban because of a live takedown, and that's something I'm fine with risking as a part-time small streamer. I have a good number of friends who are neither small nor part-time, and they'll lose their livelihoods if they're banned due to DMCA shit. It's dumb.
