We do not offer any kind of lending at this point. We are considering allowing people to have "saving accounts" managed by one of our financially-licensed subsidiaries at some point, which would come with some kind of interest rate, but we haven't been able yet to find any company willing to help with insuring and recovering bitcoin debts.
Anyway should it happen, it will be a voluntary process that will require acceptation of specific terms of services first. For more details you can read our current terms of service:
Mt. Gox represents and warrants that [...] it will hold all monetary sums and all Bitcoins deposited by each Member in its Account, in that Member's name as registered in their Account details, and on such Member's behalf.
It will be interesting to research the messages history of this mega rat.
Yeah, don't forget to save all his message before he start deleting like MtGox Twitter.
