The simpler ideas I have are to aggressively kill any snarky or pun-filled comments and raise the downvote karma limit (again...). A slightly more interesting idea would be to temporarily ban any member that does very anti-guideline things from posting for a little while, coupled with an explanation as to why they were banned. Even an hour-long ban may be effective. The GameFAQs boards do this, and while they have their own problems, not following the guidelines isn't one of them.
