Vous n’êtes pas sur Facebook, c’est pas grave Facebook vend vos données aux publicitaires quand même.

Vous n’êtes pas sur Facebook, c’est pas grave Facebook vend vos données aux publicitaires quand même.

Last week, I ran an ad on Facebook that was targeted at a computer science professor named Alan Mislove. Mislove studies how privacy works on social networks and had a theory that Facebook is letting advertisers reach users with contact information collected in surprising ways. I was helping him test the theory by targeting him in a way Facebook had previously told me wouldn’t work. I directed the ad to display to a Facebook account connected to the landline number for Alan Mislove’s office, a number Mislove has never provided to Facebook.
He saw the ad within hours.
