The forum has only two admins, and since I have been on the forum (6 years), I have only witnessed once that one admin has publicly commented on the perma ban he has personally removed...
It wasn't an admin in ReguluHr's case, but global mod hilariousandco made a short post when he unbanned ReguluHr after almost two years or waiting.
I unbanned it.
I don't remember ChiBitCTy's case and if there even was a ban appeal thread. But he was another valuable member that got banned and later pardoned.
