I took it to mean he wouldn't pay until he had control of the account, I would assume a changed password and a confirmation from payb.tc that the payout address is changed would be enough
Obviously I meant this (as I read that some are pretending to own BitcoinMax or other PPT accounts).
No one will sell his account if Pirate returns and repays all, I think.
But at the moment there is a default risk, as everybody knows...
