I don't
think the RFC process is especially onerous. Just slap
together a few diffs showing what has been done and the actions you
have taken to try to resolve the problem and how the other party has
reacted (or not reacted). Get your co-complainant, who has tried and
failed to resolve the same problem, to certify with you, along with
his own evidence. Move
Easier said than done. Locating your co-complainant is the tricky
part. You just won't find many editors on Wikipedia who's first
experience of the community was a banning. They tend to leave pretty
quickly.
Successful arbitration cases have been brought
against administrators,
some of them resulting in loss of administrator powers. Usually in
such cases there has been consensus amongst other administrators that
a particular admin has gone too far.
I think I remember one case in which the ArbCom revoked administrator
privilegies from an admin. Some admin who had a name consisting of tree
digits and was not 172. But you are talking in pluralis meaning that
you have seen more than one instance of this happening. It would very
good if you could describe the events so that we can see how far an
admin actually can go before he or she loses his or hers
privilegies.
Set a precedence, formalize the rules, so that it
doesn't
seem like admins are VIP:s with diplomatic immunity.
The Everyking RFAr proved, if it needed to be, that admins are governed by
the same standards that apply to all editors.
