Here at Reputation.com, we’ve previously talked about Foursquare and how the location-based application tracks where you are, where you’ve been, and when, allowing users to earn product and service discounts in the process. Now a new site called Please Rob Me brings that same technology a little closer to home and in the process points out the dangers of location-based technology.

The idea is based on the same concept as that of Foursquare and Google Buzz, however instead of telling the online world where you are, it tells people where you’re not – namely at home. Using data picked up from Foursquare and Twitter, PleaseRobMe.com simply plasters your last location and when you checked into your Foursquare or Twitter account on a livestream on the site (i.e. @zachscott left home and checked in 10 minutes ago: I’m at Raising Cane’s Chicken Fingers [6513 W. Park Blvd, Midway, Plano]).

PleaseRobMe.com seems a little malicious in nature, especially with the site’s catchphrase “Listing all those empty homes out there” and use of terms like “Recent Empty Homes” and “new opportunities” but the Dutch creators have made it clear they’re just doing this to drive home a point. The developers write:

“Services like Foresquare allow you to fulfill some primeval urge to colonize the plant. A part of that is letting everyone know you own that specific spot. You get to tell where you are and if you’re there first, it’s yours. O, and of course there’s badges.

The danger is publicly telling people where you are. This is because it leaves on place you’re definitely not… home. So here we are; on one end we’re leaving lights on when we’re going on a holiday, and on the other we’re telling everybody on the internet we’re not home. It gets even worse if you have “friends” who want to colonize your house. That means they have to enter your address, to tell everyone where they are. Your address.. on the internet.. Now you know what to do when people reach for their phone as soon as they enter your home. That’s right, slap them across the face.”

And they have a point, as in the case of the purported Twitter-based robbery of Arizona resident Israel Hyman almost a year ago. Now that the idea is out there and all easily accessible in one location like PleaseRobMe.com, geo app users might want to seriously consider laying off the technology – or at least make sure someone else is at home when they’re not. Or invest in a guard dog.
