"News of a file containing the personal details of 100 million Facebook users is making the rounds on the internet. An MSN reporter writes:
The information was posted by Ron Bowes, an online security consultant, on the Internet site Pirate Bay.
Bowes used code to scan the 500 million Facebook profiles for information not hidden by privacy settings. The resulting file, which allows people to perform searches of various different types, has been downloaded by several thousand people.
Since this is just a compilation of already public information available on the web, it begs the question, Why the fuss? Turns out, many Facebook (and other social net) users haven't quite considered that no matter how much they lock down their own privacy settings, much of their personal information still leaks from friends who haven't. So, for example, if you make the list of your friends private, but those friends don't make their list of friends private, it's easy to tell who your friends are. Other examples may include photos in which you've been tagged. Is this type of information leak something online social networks should attempt to try to fix--say by enshrining a principle of maximum restriction (your friends can't list you as a friend if you've elected to keep your own friends list private, for example), or is this type of leak part and parcel of being on the web?"
