All account recovery can do is switch the keys back to older keys/password if it has been changed within 30 days, such as to recover an account from an attacker that steals and changes your password.
Sadly if he doesn't have a copy of a password or owner keys that were used on the account within the last 30 days, there's nothing we can do. :/
I realized that yesterday. Thank you for clarifcation.
While walking @miketr through the process, we found out that account recovery via facebook is broken.
Yes, we got that report - we're working on the bug now. Thank you for reporting it!
