I think that post count and rank don't really matter. Crap is crap. As far as I can tell it will almost always wind up on forums. But it's just one less reason for it to be posted.
That was the idea... you'll notice the post count isn't displayed either. It certainly has cut down the poscount++ a bit (and all the topics along the lines of "look at me I've got x posts now! yay!"). However, whether it has reduced the crap or not is entirely subjective [] ]'>
