And what about the users who had their accounts compromised in the past few weeks or so?
Many were trolls who lied, IMO.
A password hash does not allow you to login. The mysterious big account might have had a virus/key-logger on his PC.
I have had $200 vanish from my account. I have turned my PC upside down, including manual analysis and found no malware of any kind. I had a 20 character alphanumeric mixed case KeePass-generated random password. I was not a victim of the CSRF exploit as I could not reach the Mt. Gox site (thus wasn't logged in) at the moment the funds were stolen. Someone could easily break such a password by using a service like Amazon AWS - and it would actually pay off as you are trying to compromise accounts on a financial service that holds money. Not to mention that miners have hardware that is specifically suited for hashcracking.
Now tell me with a straight face that this was not related to the database leak.
Maybe I was mistaken, and sorry about your loss of money.
I wish I knew you in the real world, so then I'd know for certain your story is true.
