If I create a brand new Facebook profile, and I never tell Facebook my location (neither via my browser geolocation or profile info), however most of my Facebook friends that I chat with daily live in a town called Hackerville. I've never installed or used Instagram or Whatsapp. Guess where Facebook thinks I'm living? They can be pretty sure I either grow up or live in Hackerville.
