I don't think Mods can help. They will not have access to such features.

We have account recovery team. When my account was hacked they asked me my original email address. I assume it was to verify if I am the original owner. I provided that although the email was hacked too and they knew it. But above everything else the staked bitcoin address was the key information that helped me to get my account back.

In OP's case, unless he have a staked bitcoin address (which he does not), he has zero chance. The account made 5 posts, nothing to lose if he can not recover.[/list]
