Honestly I had no idea about this rule.. If I did, I would have probably staked an address and kept the details safe.
Hes still asking 0.075 for my account he wont take 50% so there is going to be no deal. If Theymos doesn't return my account he should at the least destroy it, so no one else gets facked....
As much as theymos would love to restore this account back to you, he can't, for he has to follow his own rules and therefore his hands are tied. See if you can find an old address to sign a message with and maybe then he will be able to help.
