Just ask for a signed message from an old address already staked/used here
If he can't provide
probably this account was sold, and it's 40$ request it's just a scam attempt

It doesn't look like the 1MaStEr address belongs to him, According to the post he was asking about that address.
He doesn't have anything to prove he is the original owner of the account.
@marcelus: Do you remember any additional info about the trade you had with qwk that only the real marcelus could know?
If you do you might be able to get qwk to confirm that your the real owner of the account.
