So, how would they go about giving the used copy buyer their "entire account?"
Exactly what does that mean?
Thanks,
Pretty clear: access to the email used for RoF and the password.
There's nothing easier than creating a free gmail account and having it forward to your ordinary email (so you don't need to log in to and out of several accounts). I am guessing that most of us have a "spam mail" we use like that. I certainly don't give out my ordinary mail address for all purposes.
