I wonder if they have a file on me, even though I don't use facebook and a lot of blocking tools. Anyone tried? Not even sure how to request the data, when you have no account .
Friends and family install Facebook mobile app, all of their contacts are sent to facebook which includes your phone number and email addresses. More data is gathered from other random sources online. Possibly even pictures from your college or mugshots.
Just imagine the data that was taken from the people who installed that LinkedIn "send all of your email through us" app.
I've heard that Facebook create ghost profiles based on things like known contacts (contact sync by a user) of users, so probably. What they'd use that for is less clear, although I assume their legitimate reason is for making better recommendations to new users and maximising early engagement (I seem to recall they have research papers on that topic).
