Surprise! Surprise! Facebook was recommending all the people from my deleted account magically to my newly created account which has nothing in common with my old account except for the mobile number.
For all those sharing content in FB, worrying about your privacy is pointless and a total waste of time.
My personal opinion is that, Google somehow values people privacy more than Facebook, that why its social networking attempts are failing. On the other hand, Facebook is just ruthless when it comes to handling people's data and that is why it is having much success as a social networking platform.
