How is this any different than FB asking for access to your private contacts, to "help" you find them on FB? What if one of your friends isn't on FB, and doesn't want FB to have their info? Your friend didn't give you permission to give FB their private contact information, ie phone number. FB then goes and makes a shadow profile based on that info you supplied without permission, and any time you mention or tag said friend, whether in a text of photo.
