The same people who hate him now for this were hating him when he was 15 and doing nothing wrong and now revelling in the fact that they have some genuine (if petty in the scheme of things) reasons to hate him. All very bizarre behaviour from people who claim to be superior to him. If his existence offends you that much you'd be better off ignoring the whole thing.
Trying to be reasonable on the internet, not even once.
