I remember a Rei from a very long time ago. Everyone's post count is 0 now, so it doesn't matter. The only other bits of information that makes a user account unique is the registration date (I can change that), username (I can change that), other profile information (you can change those yourself), the posts you've made (most if not all of those have likely have been pruned by now), and user ID number in the database (not at all important to anyone).
