I am troubled by User:Guanaco's behavior here.
He does have a valid point that banning Michael seems to not work. He only comes back with new accounts or edits via IP, and does the same thing. It may indeed be easier to "contain" him to a known account or two and then just pick up the pieces.
HOWEVER, I don't think it's Guanaco's place to unilaterally decide that this should be our new policy. He is still officially banned and bannable on sight. If we want to alter this decision, let's discuss it in a place of record (here, or on Wikipedia).
