I signed up for a Mt. Gox account ~12 months ago and included my drivers license. I then cancelled the account a few weeks later after one of the many Mt. Gox incidents. A few months ago when the price skyrocketed to $1000 USD/BTC I reopened my account with Mt. Gox. They didn't require any further information from me, just a a request to open the account. I took from that that even when an account is cancelled/deleted, they still retained all user information including drivers licenses. Even if you deleted your Mt. Gox account before they went bust you may still be at risk.
