A  website called PleaseRobMe claims to reveal the location of empty homes based on what people post online.

The Dutch developers told BBC News the site was designed to prove a point about the dangers of sharing precise location information on the internet. The site scrutinises players of online game Foursquare, which is based on a person's location in the real world. PleaseRobMe extracts information from players who have chosen to post their whereabouts automatically onto Twitter.

"It started with me and a friend looking at our Twitter feeds and seeing more and more Foursquare posts," said Boy Van Amstel, one of PleaseRobMe's developers. "People were checking in at their house, or their girlfriend's or friend's house, and sharing the address - I don't think they were aware of how much they were sharing."
