I have yet to see any actual evidence (other than his use of the name) that Wik was in fact the person who posted that material on your talk page. I think you are still "dictator" in any circumstance you choose to be. Your problem, usually, unless somehow you were personally involved, is not knowing the details and having to spend of lot of time researching things before you act.

But I think it would be fine, and safe, if it were clear that I still can ban in some extra-ordinary cases, particularly since I would also be honor bound to respect the outcome of an appeal to the arbitration committee.
