Mt. Gox is indeed full of shit. As I understand the issue, due to their bitcoin implementation, there is a possibility that someone would send bitcoins from their Mt. Gox. account to a wallet, than alter the signature of the transaction, and than claim that the transaction did not go through and contact support to request the funds to be resent. Here are 2 easy solutions to this problem which do not require anything to be done by the bitcoin community, and could be exacted by Mt. Gox today: 1. Allow all transactions to go through as before, but state clearly that if your transaction does not go through after being submitted, it will take a long time to clear the transaction, because it will have to be checked by hand. Assuming that 90% of people are not planning to scam Mt. Gox, 90% of people would be able to get their money. The remaining 10% would have to wait a bit longer while Mt. Gox checks transactions by hand. 2. Alternatively, write a system were a user can request to withdraw bitcoins. The Mt. Gox server first generates a new wallet, than transfers the BTC to that wallet, than send the user the public and private keys for that wallet. Assuming that the user (for good reason) does not trust Mt. Gox, they than can simply transfer the BTC from a temporary wallet to a permanent one.
