I'd say ban petitions, but I'd be gone in an instant. The forums should be a republic, we elect moderators that have our opinion.
I disagree with any form of voting.
You know how people get around here.
Voting against banning obvious trolls so they'll be 'cool and hip' and be acknowledged by these 'rebels'.
Voting to unban people who cause obvious problems, so they can go "Hey you can thank me! Now be my friend!"
