xQc is just an edgy entertainer with a short fuse. I wouldn't class him as a bad actor because I don't think he intentionally tries to ruin things.
Twitch chat is also a completely different beast that no one controls.
Not only is he not managing his fanbase, he is actively encouraging stream hopping. Moreover when he was banned from nopixel yesterday, server got ddosed into the ground afterwards ruining other people's streams.
The last incident? Yesterday [1].
