A study of data on 13 million Foursquare accounts showed that researchers could infer “with high accuracy” where a particular user lives based on their accumulation of mayorships, check-ins and tips. Specifically: the researchers could correctly infer the home town of the Foursquare users 78% of the time, within an accuracy of about 50 kilometers. Security Ledger has the story."
