i have an account from when i was a teenager that i sometimes use to talk to family. why do you ask? based on my anecdote we are all tracked by facebook, whether or not we are on facebook.
I am not sure how your anecdote would show you are all tracked by Facebook even if you aren't on facebook; you only received recommendations for people to friend on facebook because you are on facebook. I am not on facebook, so i have never had facebook recommend anyone to me.
