TOPIC BANNING

Well, I thought of an idea for topics that become flame wars. What if moderators are given the ability to ban certain members from topics if a flame war begins, instead of locking the topic or banning the member altogether? This is just an attempt to try and salvage some kind of intellectual debate between members, and also gives a greater chance of people getting to voice their opinions instead of reading through locked topic after locked topic that resulted from a flame war that broke out, and lets them continue posting and makes the flamers stop. This is just a suggestion mind you, and I've never seen it done in any other forums and think that it's possibly a good idea. Although I could be entirely out of my mind on this one and might make the forums for lax for flame wars. So anyways.. yay or nay?
