Also, the message verifies.
Have they lately helped in recovering any of the hacked accounts, where signed message was presented?
Mine was hacked a few weeks ago. The first messages I sent to both theymos and Cyrus contained errors, so I was pretty hopeless by then. Luckily, they reconsidered and Cyrus reviewed two new signed messages from two different addresses that I posted on 2015 and I got my account back. The thing is if you haven't posted any sufficient evidence about your ownership of the account, you will be ignored.
How long did you have to wait before you regained control over your account?
I know of another user "Yefi" who has recently got his account back too.
I did send both admins a copy of the signed message above so hopefully not too long.
