If they're narcissists, then yes, because a narcissist is perfect, and each of his traits is a gift to humanity, so he wouldn't hesitate to describe how he sees himself, in gory detail. This obviously argues with the meaning of "honest answer", unless we accept that an honest answer is anything a person believes to be true.

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.
I don't really find it that interesting when people just try to troll and cause havoc for absolutely no reason at all other than their own amusement. There should be an appropriate target who has been flapping their gums and needs to be brought down a peg.
Pretty sure I managed to do the whole thing without explicitly lying, either.
Actually using the word "killfile" probably puts you on a terrorist watchlist.
