Thread bans

It is known that there are people who troll online forums, and while I am all for freedom of expression if individuals are purely acting in a way to disrupt a thread then could it be possible for the thread creator to put a ban on specific individuals who are acting contrary to the threads intention?

All bans should be considered carefully, and perhaps a maximum num ...[text shortened]... ught, because there are some threads that are utterly ruined by people acting without consideration.

I like the idea, but there might be forum-gamers who would either abuse such a function or see it as a challenge to overcome, work around, or turn against itself.
