Twitter homepageThese days most of us are either tweeting, poking or instant messaging.

But the problem with social networking is that we reveal too much about ourselves and our lives – and one website has proved just how dangerous too much information can be.

The site, called PleaseRobMe, claims to reveal the location of empty homes, based entirely on the information that people post online.

Speaking to the BBC, the Dutch developers of the site say that it was designed purely to prove a point.

PleaseRobMe scrutinises players of the online game Foursquare, which is based on people's actual locations.

The site then extracts information from those unfortunate participants who have posted their whereabouts automatically onto Twitter.

Boy Van Amstel, one of the developers, said: "It started with me and a friend looking at our Twitter feeds and seeing more and more Foursquare posts.

"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."

After realising just how much personal information was readily available, the developers took just four hours to create the site – but they stress that it is not aimed at encouraging crime.

"The website is not a tool for burglary," said Van Amstel. "The point we're getting at is that not long ago it was questionable to share your full name on the internet.

"We've gone past that point by 1000 miles."

So be careful what you tweet, folks... you never know who might be watching.
