Holdaaja: 5 bitcoins have left that account today and I haven't received any messages, at the very least this trade has been handled poorly regardless of what's going on in his life. If he can make time to move coins around he can make time to send me boa or btc.
sorry if i've missed this but are you sure it is not a web/shared wallet? many web wallets shuffle funds around from addresses without necessarily moving it from the account
