Debating doesn't garuntee flaming. I think its a great Idea, but if you are that worried about it, then we should have a sub-mod that takes care of that section. One who doesn't just delete posts if he THINKS that its flame. Most stuff is not actually flame.
I knew you were going to make a thread. Just because you got banned, doesn't mean you have to go and be immature about it. When slip bans you, he sometimes unbans you a few minutes/hours/days later. Depending on what you did.
