I tend to believe him, but it would be better if the original owner made an alt account here and signed a message from a staked address and argued for the hacking himself.  Then I would tag the account with no hesitation. 

What if it's a sold account?  I'm reluctant to take anyone's word that they know the owner of an old account personally, no offense eddie13.  It's just that I'd rather hear it from the alleged victim himself and have some proof.  If you do really know this guy, why don't you suggest it to him?
