Is there something I can do about a corrupted FC?

Really all you can do is report them to a GM, explain the situation, and let them make a judgement call on if any rules have been broken. Otherwise leaving and blacklisting are your other options.

He isn't even in the FC, and heard of all the information second-hand. Suggesting he contact a GM is a complete waste of time, for both him and the GM. On top of all this, it's been shown time and time again these situations are within the rules, because of the permissions system with the FC chest.

There's no need for him to white knight over this or seek social justice. Again, he isn't even part of the FC he mentioned.
