Facebook recently closed a privacy loophole that allowed third parties to discover the names of people in private, "closed" Facebook groups. A Chrome extension that was made specifically for marketers to harvest this information en masse was also shut down prior to Facebook's move, after the social media network issued a cease-and-desist letter to the application's makers earlier this year, according to a spokesperson.
