Facebook Quizzes Get a Failing Grade for Privacy

Even if your Facebook profile is "private," when you take a quiz, an unknown quiz developer could be accessing almost everything in your profile: your religion, sexual orientation, political affiliation, pictures, and groups. Facebook quizzes also have access to most of the info on your friends' profiles. This means that if your friend takes a quiz, they could be giving away your personal information too. (But, again, don't just take our word for it: !)

And Facebook's restrictions on the collection and use of personal information by applications are simply inadequate. Although Facebook's require that applications only collect and use information related to the app itself, enforcing this rule may be really difficult. That means that random developers who ignore the rule could potentially sweep up vast amount of personal information about you and your friends — and once they've collected it, they could easily sell it, share it, or even turn it over to the government. This is a major privacy hole, and Facebook needs to take stronger steps to address this problem than just writing a sentence in a rarely-read document.
