What is wrong with my post counts

Why does my forum keep coming up with crazy post count numbers?

Wow, you've got some real Post Wh*res on your site!

Do you have any mods installed that may be affecting the post counts? Is it this way in the database or just this way when being spit out on the page?

There's a mod somewhere messing with something. What have you added from the time things were normal until the exaggerated post counts?
