Ah trolling...
Can I admit that I love it sometimes? Having spent quite a bit of time on various internet forums, i've seen quite a few of these, especially during my WoW years. But every once in a while, I end up making a friend out of a really good forum troll. And I mean really good.
What I mean by a "good troll" are the people who can use their words to really piss someone off, and yet never get in trouble for it. The kind of people who are really subtle and say nothing that is obviously offensive. Indeed, the troll post might not affect anyone else but the intended target. And, of course, the ultimate objective of trolling is to piss the other guy off enough that he gets in trouble himself while the troll simply walks away with a smile on their face. That, to me, is a good troll. The bad trolls are the ones who get caught and punished, which is a large majority of trolls.
So... I like good trolls because they are hilarious and often very awesome people to spend time with. Bad trolls though... they're just annoying, and thankfully they tend to go away fast because they get the banhammer.
Trolling is an art. An art that most people are shit at. But when you see a good one... it is awesome. XD
