he can also make his Facebook so only his currant friends can see any of his posts. He will have to go into his account privacy settings and change things there...I believe.
He also does not have to accept anyone as a friend if he doesn't know them and in fact he can report them. It is illegal, on facebook, to solicit strangers as "friends" from people you don't know. Or at least thats what I was told.
