"VTubers should have the same sort of attire as actual people on Twitch."
It's worth remembering that #Twitch is a website with a background centered around video games. Video game characters / games have a wide range of expression. On the other hand, content involving actual people wouldn't align as closely with the video game theme (even if censorship is problematic here too).
A VTuber is a lot like a video game avatar, a video game avatar addressing an audience, maybe, but it isn't as much like someone performing in person. #anime
