The professional way to deal with trolls is to delete their posts and ban them. If a troll continues to make the same thread over and over, watering it down slightly after every time it's deleted or closed, why should the one that's just right according to you be allowed to stay the boards? The motivation behind it remains the same.

If you feel that there is an issue to be discussed, you are free to make a thread about it. Just don't lie, insult anyone, or make random accusations.
