The dangers of geotagging posts has already been well documented. In 2010, a report by the International Computer Science Institute (ICSI) showed it was possible to get the home addresses of people who had posted photos in ads on Craigslist, despite those people having opted to keep their addresses hidden in their postings, by using the geotagging data on photos that many digital cameras and smartphones automatically include. Even with geotagging turned off, in 2014 IBM created an algorithm that predicts a Twitter user’s location with 58% accuracy.
58 percent? When I look up ads of craigslist in the Dallas area I pretty much know the area the post is coming from. The drop down box with the preferred area is a big hint.
They need an algorithm to predict that?
