You need to sign a bitcoin address associated with that account, before any admin look in your problem.
https://bitcointalk.org/index.php?topic=497545.0I hope that you will recover your account, I try to browse to the posting history and I can't find a bitcoin address in page 83-84, but it's your account so you should have a bitcoin stake address somewhere.
I already posted a sign messaged using ETH and it is posted above with all the proofs I have, And I think that one I posted is strong proof.
Etherscan verifies me.
