People HAVE tried to cancel him, but I think the main reason it doesn't happen is because most people outside of twitch (and even some inside) don't know who he is, and those who do, know that's his brand of humor. He's gotten much better about staying relatively tame as far as PR goes, due in no small part to Alluux's oversight, but I think the wubcubs do a pretty good job of shutting down cancel attempts.
