theodp (442580) writes "Betabeat's Adrianne Jeffries takes a look at the questionable young science of using social media to evaluate creditworthiness. As banks start nosing around Facebook and Twitter, Jeffries explains, the wrong friends might just sink your credit. 'Let's take a trip with the Ghost of Christmas Future,' she suggests. 'The year is 2016, and George Bailey, a former banker, now a part-time consultant, is looking for a 30-year fixed-rate mortgage for a co-op in the super-hot neighborhood of Bedford Falls (BeFa). He has never missed a loan payment and has zero credit card debt. He submits his information to the online-only PotterBank.com, but halfway through the application process, the website asks for his Facebook login. Then his Twitter. Then LinkedIn. The cartoon loan officer avatar begins to frown as the algorithm discovers Mr. Bailey's taxi-driving buddy Ernie was once turned down by PotterBank for a loan; then it starts browsing his daughter Zuzu's photo album, 'Saturday Nite!' And what was this tweet from a few years back: "FML, about to jump off a goddamn bridge"?' So, could George piggyback his way to a better credit score by adding Larry and Sergey to his Google+ Circles?"
