Give me a break. The "It wasn't me, it was some one else using my name" is the oldest excuse in the book. I feel bad about the car accident, but I don't believe for a second that it was other people using his psn account. Why not turn off auto log in and make sure the password isn't there if you know others are going to use your console. Let them make their own psn name on your console instead of logging into yours.
