https://bitcointalk.org/index.php?topic=990345.0Find your locked account in the "search members" area and on that account profile, click "last posts of this person".
You need to find an address YOU posted BEFORE the account was locked.
These requirements are the best way to prove that you are indeed the account owner, and are standard procedure
here. Goodluck!!!
