accounts are being sold all the time here. there no excuse by not using escrow, IIRC the fee on bitmit is around 1.5%
I've never used bitmit before, but I thought most escrow services have a minimum charge. I can't believe that anyone would want to pay the $1 min charge for a 5 or 10$ GC (which is apparently the denomination people trade in nowadays) but if they want to then by all means go ahead!
And I can send a signed message proving that I still own this account if anyone wants. There are plenty of ways to ensure security, only one of which is using escrow. For smaller transactions I've down things such as video chat with people, given them my personal cell to call me and chat first, etc. Once again, look at my history. I bought a $10 GC earlier today on this forum and instead of using escrow, I just asked him to do the payment of the deal publicly so there would be a record of it. I doubt anyone was going to risk their reputation over $10 when they have already built up rep. I will do the same for anyone who has already built up rep (I will go first) but my message was directed at newbies who have no rep as of yet.
