His account was inactive for quite a while, so I don't think that the real owner has even noticed yet. He may have left the forum.
Maybe the real Wardrick sold the account ages ago - just a thought.
but why the owner didn't buy his private keys too?
and why he is not using the account anymore?
DT accounts are pretty expensive to have one just without use in your inventory
If ages ago = before he becomes DT, then I don't thin it matters
