In 1934, George Orwell predicted a bleak future in which a mysterious entity known as Big Brother tracked each citizen’s every movement using giant television monitors. He likely never imagined a day would come when people would readily tell such an entity everything about themselves, from what they ate for lunch today to what they are planning to do tonight.
It is true that individuals bear the ultimate responsibility for the information they make available over the Internet. Unfortunately, Facebook does not have a good track record of helping its users protect the information that they share with other users. While Facebook does offer settings which limit how much friends, friends of friends and non-friends can see on a user’s profile, those settings were reset for everyone back in 2009 without any announcement from Facebook. What’s worse, they breached their own privacy policies a year later when they started selling user information to advertisers.
