Personally, I've always preferred moderation controlled by the client (i.e., a killfile in a NNTP client) rather than relying on moderators. That way, I can decide what I see. Theoretically, bad actors would end up in everyone else's killfile, but in reality, it never really happened. Some clients at least allowed hiding a subthread so that you wouldn't see messages that were essentially a dispute between two people. But one way to slow down the flame wars would be to rate limit the number of comments that can be posted. If you require people to wait 10 minutes to post a subsequent comment, that would definitely slow down the discussion and probably would lead to them moving on to something else.
