Not sure whether that would be a good hack. If there is a heated conversation going on legitimate users can certainly create many posts within a certain small period of time, especially if two people argue a point between them.

In my board rules I specifically state that postcount bumping is not tolerated. Those who are found countbumping can be banned. Alternativly you could disable or freeze their postcount.

I guess I am saying that identifying spammers should be an admin/moderator job, because automatic methods of detecting such spam could easily lead to false positives and upset legitimate posters.
