This has been the most oligarchic policy on wikipedia since it was created. Obviously an anon can't "Ignore All Rules", he'll be banned. When an admin "ignores all rules" and is justly banned, he unblocks himself. Thats the spirit oif the rule.
In my experience this policy is yet another excuse for the old hands to bite newbies and those outside their clique. It's an unprofessional policy, in fundamental contradiction of the rigour required for the creation of an authoritative book of reference.
