Furthermore, and of foremost importance, Milo did not actually direct anyone to do or say anything to Leslie Jones. You could say he fed her to the wolves, but she was already receiving pretty significant criticism by people who didn't like the new Ghostbusters film beforehand. He never said "go get her" or anything of the such, it's not like he made some abusive hashtag like
#CutForBieber telling people what to do. People acted of their own will, Milo didn't recommend abusive language toward Leslie, saying he "incited it" is pure opinion, almost like saying a celebrity incited a user to reply to one of their tweets with "FUCK ME DADDY" by posting a photo of themselves. Not their responsibility what other people say or do, which is why being banned for "inciting hate speech" holds no weight. It's not something you can prove. The best you can do is claim he led by example, which doesn't merit a ban.
