Yes, but some trolling is a genuine gift to humanity. I've seen (and executed) some truly celestial-- even operatic-- trolls.
By the way, I can't stand online bullies. Those assholes ruined trolling IMO. Trolling was awesome when what happened online, stayed online and no one ever tried to fuck with another's "IRL" existence. The problem is that, while the skilled trolls tended to stay white/gray hat-- shit, some have said that I'm an extremely-white-hat troll-- the unskilled trolls had nothing other than evil to distinguish themselves. Eventually it became repulsive.
