ATCsecure said it's possible for this thing to happen until he employs the trust system. Go back to your cave.
which is why it's really a non-issue. he has stated current release is a beta and has told users to use its features at their own risk. REV2 which will eliminate this risk will be released soon.
You cannot eliminate the risk by a trust-algorithm. You are just delaying the inevitable (stealing).
You trust once, you trust twice, (increases number and sizes of transactions that comes your way) and then BANG... the bank robbery when a large tx comes.
