For example, good trolls could be pedants/mini-mods, evil hackers could be black hats, etc.

How do you have a good clbum that causes just as much trouble for forums as the bad ones do? You can’t say the good troll has a conscience and feels bad about hurting people because he’s still a troll, and by definition they want to cause disruption. I can see good hackers not taking certain missions because of ethics or whatever, but how do you have a good emo, camwhore, or permanoob? Emos don’t care about anything, permanoobs are too stupid, and camwhores…

Though it would be funny to make a joke about how they’re exposing themselves for justice and whatnot, it doesn’t make much sense.
