Just create and use new account.
Themos rarely recover accounts and that too like hero or legendary.
You can create a new account depending on ehy you got your account banned or locked. Don't try it if you are banned from the forum cause it will be considered as ban evasion.
Theymos and Badbear do recover accounts, not just Legendary and Hero accounts. I once got locked from this profile because I use my secret question to recover my password. Badbear helped me recover it. All I have to do is prove the ownerahip of the account.
A signed message will help also use the email you use to register here in the forum in sending a message to their email. That way your issue will be noticed.
I already sent pm to theymos and Badbear to look at this thread around half an hour ago.
But later I saw this one :
https://bitcointalk.org/index.php?topic=497545.0So I again sent a pm to theymos in the same format as mentioned by him.
Hoping for something good
