Allow moderators to reduce visible post count by a certain amount?

[Darth Cow]

I'm a super moderator on the mtgnews.com forums at forums.mtgnews.com

We have a problem with users spamming to up their post count and user titles.

We've been giving users "warnings" when they spam or flame someone, and after a certain number of warnings they are suspended or banned (manually).

Is there any way moderators could be allowed to reduce a user's visible post count by a certain percentage? For instance, one someone spams, could we reduce the post count by 5% to make them pay attention.

I suppose this is a request if it can't already be done. Our administrator is very busy though, and I'm doing this to see if I could save him time. Because I don't actually own the forums, that's why I can't post this in the request forum.
