Facebook knows too much, ACLU says in warning of quizzes

Privacy advocates have long warned that users of Facebook and other social networks who seek amusement from quizzes like "What Simpsons Character Are You?" might be mortified by the way creators of such applications can access and potentially "scrape" personal information — not just about the quiz-takers, but their friends as well. Now, engaging in some online jujitsu, the ACLU of Northern California is employing a cautionary Facebook quiz of its own to illustrate how quizzes that may seem "perfectly harmless" can release an array of data to the wider world — including users' "religion, sexual orientation, political affiliation, photos, events, notes, wall posts, and groups." The app, titled "What Do Facebook Quizzes Know About You?" delivers its answer by opening a window that scrolls biographical data, attributed comments and photos. More than 8,000 participants have taken the ACLU's quiz since it was quietly released a few days ago, the ACLU said Wednesday. The group hopes to prompt Facebook to upgrade its privacy default settings for its users, now numbering more than 250 million.
