Bitcoins ok, but how 40k dollars disappear? how withdrawn? I do not know how mtgox codes work, but you can not really know where are redeemed? Other options dwolla? OKPAY? Bitinstant? LR? I really can't believe that you can move dollars without knowing where, how and to whom.
We know how and where the USD moved, but unfortunately those funds are not under our control anymore.
Well, no shit they're not under your control, but you do know to whose account they moved, right?
