Nothing wrong with streaming nudity, but Twitch is specifically marketed to children for the purpose of watching people play video games. Blending porn in that with an algorithm that throws new videos in your face is a recipe for disaster.
Your “supposed to be clearly labeled” argument is really doing a lot of the heavy lifting here and ignores the reality of people gaming the system or finding loopholes and we all know there aren’t going to be any real people moderating the site just like every other social media/video streaming site.
They really should have split it up into two different sites because I see this blowing up in their face spectacularly.
