Listen if a trusted member of the site can verify this person claiming to be the "rightful" owner is indeed the rightful owner?
I'll be glad to hand it over without issue. Just let me know!
The account is safe and in good hands, and IF the account was hacked? It will be given back to its rightful owner without hesitation.
Did you receive a signed message transferring over ownership of the account to you when you purchased it? I'm afraid if you don't have any signed message proof, "funkymunky hacked" will probably be able to get the account back from because he has proof of ownership from last week.
