I bought a digital download of a PS3 game on ebay, but instead of sending me a code or key or something, the seller gave me a Sony Entertainment Network username and password. His instructions were to create a new user, choosing this account for it, then download the game and then sign back in as me and play the game.
(This is all a bit shady, I thought, but the game was a good deal, and I don't mind a few hoops at the start if it's technically legit).
But can the seller do anything to my PS3 or saved games or my own account if I do this?
Can he just wait a few months (to avoid bad feedback) and then remove my access to the game by removing my PS3 from his account?
Edit: Got refund easily through eBay. Thanks everyone.
