Yeah I noticed that, maybe the forums sensed the 'dark side' surround him (Micro$$haft) and decided not to do anything about the post count.
hm.. after a quick test I think that the post count doesn't go up in certain forums, like the news and article one. Mine didn't, but did in response to this. So thus, it isn't broken - also testing doesn't have an increment I believe, to stop people bumping their post count with spam, perhaps?
