Confidentiality: Only the buyer and me knows the buying of accounts takes place.

The reason I got redtrust is for only selling accounts not from scamming.
The fact that you don't use escrow suggests that you may not actually be selling anything and the way you operate is ideal for a scam. Individuals who decide to do business with you are anyway cheated in one way or another, because either they will get nothing when they pay, or they will get a BTT account whose history they will not be able to adjust to.
In other words, the new owners will be identified and tagged very easily and quickly.
