As for "hate" I haven't seen it. Unless you think that in game emotional posts are "hate"
Fans post outrageous emotional things during the eb and flow of a game. That doesn't mean it is "hate" it is just fans being emotional/passionate of what they are seeing.
If a guy posts heavy criticisms of a players game or poor performance IMO it isn't hate, it is opinion. Nobody is saying they hate him as a person, but they may "hate" the way he closes out a game. It is all just a matter of opinion and that is what CB is for.
