Actually, Wolfgang, if you change your 'catter ID, all your posts you've previously made change with it (I believe). I know there's nothing left under my original screen name, and my current one extends back to when I joined... That's probably the difficulty you're experiencing.

Now, one or two names HAVE been deleted - cases where the troll has decided to try usurping someone else's identity.

Other than that, any changes are likely the result of the member changing their name, not the admin Elves.
