Hi, Pachyerm.

I think I can help you with that.

When a member asks for their account to be deleted. It deletes their username, and goes back and fills every post/thread in with Anonymous.

The posts remain the same historically, so if they signed their name, or someone referenced their name, it will still show in posts.

If you see "Anonymous" as a username, it's someone who's account has been deleted by request...whether or not they've returned with a new or the same name.
