Anthere-
But I think it wrong regular users can not from time
to time check whether pages were not unproperly
deleted (not along community defined rules).
On en:, someone created [[Wikipedia:Censorship]] a while ago to complain
about such incidents. I don't think it's the best title (who would want to
be labeled a censor?), but such a page would certainly allow for the kind
of feedback you envision.
