My friend received an email saying a Germany IP address 188.93.8.82 logged into his Mtgox account and made withdrawal. He then came into the account and saw several withdrawals like this:

The hacker made several 1 satoshi withdrawal but very high withdrawal fee like 2 or 4 BTC. All withdrawal fee are paid as network transaction fees to miner. You could see the satoshis gone to this address:

Several questions:
Does the hacker laundering the stolen BTCs by transaction fee? Then how could the hacker make sure he got the block mined?
How could Mtgox even allow this to happen? At the Mtgox withdrawal page there's "Pay 0.005BTC Fee For Faster Processing (Required for Transactions below 0.01 BTC)", but that doesn't mean such huge fee could be paid.
The mining fee all went to BTC Guild. We are trying to contact BTC Guild and hope to get some coin back...
