Quote from theymos : "If you want us to recover a hacked/lost account, you need to prove that you own it. Typically, the only acceptable method of proving ownership is by signing a message (including current date and desired new email address) using a Bitcoin address or PGP key associated with the account. A Bitcoin address or PGP key is associated with the account only if the account posted the key/address, sent it in a PM, or if it is still listed in the account's profile.

I very rarely recover accounts if you can't prove ownership as described above."

This means, either you provide a Bitcoin address or PGP key that is associated with the account and are able to prove ownership of it. If you are unable to do either of these, then you are likely not going to receive your account back. As hilarious has said, they can't get the message to verify and neither can I. You're providing an unacceptable address, and even that doesn't check out.

Are there any PGP Key(s) or Bitcoin Addresses associated with the account?
