Ok, stupid question. I assume that a banned user would be blocked
along with any socks he has so just how would he post or edit anything
in the first place? Post anonymously and say "HEY, IT'S ME, BANNED
USER ON WHEELS!!! The only other way is for him create a new sock,
perform some kind of dickery and someone does a checkuser. Even then,
would somebody necessarily know he's banned until he's blocked again?
