I'll tell you what I did, I bought coins and transferred them out of there ASAP. The official line is that their bank will only do 10 outgoing USD wire transfers per day period. Of course limiting outgoing transfers is the same strategy you would want use if you were financially insolvent and wanted to forestall a run on the bank.
