Remember Please Rob Me, the site that got national attention early last year by aggregating your Twitter and Foursquare location-based data to let potential burglars know you were out of town? (The service has been pulled down, by the way – go to the site and you’ll find the following statement: “Currently we’re looking through the emails we’ve received regarding the future of the website. As soon as we’ve thought of a suitable way to continue, you’ll find it right here.”)

Welcome to Please Rob Me 2.0: It’s a desktop app (Windows and Linux only so far) called Creepy, and it digs into your tweets and Flickr posts for any geolocation data it can find. On first glance, that’s not much different than Please Rob Me, which supposedly encouraged us all to think a little harder before posting that Foursquare check-in. However, by adding Flickr to the mix – which, granted, is fast losing market share to Facebook photo albums – it calls attention to a detail on the social map that many of us have forgotten about: Photo geotagging. Got a smartphone? By default, most of them encode GPS data in the photos you snap, send and post online. So, depending on where you post it, putting that sweet photo of your new stereo system online for your friends to see may be opening you up to more than you think.

Before you panic – which I did, and double-checked on my own profile photos – Facebook strips geolocation data from images. Photo tweeting service img.ly, which I used religiously for a while? Not so lucky. Your mileage may vary depending on the services you’re used to using – so if you’re concerned, take a few minutes to download your last image posts and examine the photo metadata. (Here’s how to do it on a Mac, and here’s info on photo geolocation in Windows Live Gallery.)

Scared by what you find? Consider disabling photo geotagging in your smartphone’s preferences. Or – and this may be a good rule in general, regardless of geolocation data – avoid posting photos of your home, office or any other location you don’t want to give away. (That means, though, no cute photos of your colleague’s baby shower, unless you only post them to a site you’re certain strips out GPS info.)

Is this sort of geographical pinpointing a concern for you? If so, what have you done to manage any fears you may have? Let us know in the comments.
