Any trusted escrow will tell the admins the name of the account being sold, and it will be removed really quickly from default trust.
So the only choice is trust OP and pray that no one discover you, in the very unlikely event of he delivering the account and it really being from default trust
Not necessarily. When I escrow account trades I respect need for privacy of both parties involved in the transaction. I wouldn't reveal the account to the public or the admins. If the admins really wanted to find out I am sure they can anyway. I don't think it's fair to abuse the trust of people who wants to use my escrow services to keep themselves safe.
