Just my 2 cents as a man with more than 20 years of BBS and forum experience: moderators have difficult jobs. And sometimes their judgements fails.
and
pprune is that the rules are rarely if ever stated, and while we have the nicknames of the mods, when they act it is (in all cases I know of) anonymous.
all of which suggest you (we) dont know why, so it is difficult to claim their judgement has failed.
