actually it doesnt matter if you delete your account. if anyone remembers the story a year or so ago facebook changed their privacy policy at that time to say that even if your delete your account it will stay on their servers forever and they will be allowed to use your deleted account or any other account for/in any of their advertising and you wont get a cent for it because you agreed in the very beginning when you signed up to abide by their rules and continually agree to abide by them as "these rules are subject to change at any time". but as we recently learned noone reads that huge policy when they sign up for anything.
