The original user Barfbag666 was not blocked for vandalism it was the username similar to HAILXSATANX666.  Barfbag666 could have changed their username to HAILXSATANX666 and continued writing.  Had Barfbag666 changed their name, it would be agreeing and bowing to the viewpoint of the blocking administrators which was obviously biased.  That's the point, it's not NPOV.  So logically even if they were the same user it's irrelevant.
