With this hack, any time a post is deleted (be it via Pruning or by the user himself or the moderator of the forum, and whether you are deleting an individual post or a whole thread), the user's post count is *not* affected. So this makes his count truly a full count of the total number of posts he has made since registering. The reason it works this way is all the different ways to delete a post - pruning, moderator deleting, user deleting, thread being deleted - rely on these two functions to work. Once you remove the reduce count functionality from these two places, no matter how a post is deleted, the user's count stays the same.
