I let a friend use my account and he has now changed the password and e-mail address on it. I have the e-mail address but doesn't help that I don't have access to that e-mail account. I know I can call sony and change my e-mail address and then have the password e-mailed back to my address. But I was wondering do they check where someone has logged in at. Or can they tell that the account has been shared and do anything to it? Or is it just a really easy process.
