Haahaha, as soon as they know the account has been sold, all trust will be removed and the account will not be default trust anymore. Default trust should not be something you can just "sell", you have to earn it, and clearly you did, so why would you sell it?
GPG encryption will be used so even the admins cannot read PM's between myself and the buyer/escrow.
Passwords change between accounts all the time, a lot of accounts would be removed if every account whose password was changed ended up getting removed from DefaultTrust list
