Is there anything being done about false bids?

Well considering you took the offer on your own accord I don't think there's anything we can do about it.
If it were an actually bidding thread and he won, but refused to pay, it would be another case.

That is just what conclusion I would come to by following the rules.

It might be a special case, though nothing I (and the other staff) can do about it as like I said, I and staff simply follow the rules.
Your best bet would probably be to wait for an reply from Aoki or Sozin.
