Ah. So this is something like US DHS coming to raid the accounts of Mt.Gox affiliate Mutum Sigillum at Dwolla.
The Chinese exchanges are then adopting the practice of Coinbase, the situation sounds much the same (Coinbase initiates ACH transactions with your bank and makes you wait the 5 days until it clears to actually receive and withdraw your Bitcoins.) Mt.Gox works the same way now, except last I heard their Japanese bank was limiting them to some absurdly low number of ACH transactions to USA, like on the order of a maximum of 10 per week. Coinbase, being a US company with their choice of banks, obviously does not have this restriction.
