Threat Level:  “The site set up to locate long lost pals, Classmates.com, has been hit with a class action privacy lawsuit.  It alleges the company violated the law when it decided to make user profiles public to compete with Facebook.  The suit says Classmates.com duped its paying customers in late January when it sent them an e-mail telling members they’d have to opt out of new Facebook and iPhone apps to keep their data private.”
