It’s hardly Facebook’s fault if you splash that stuff all over the web. Is it…?
Nope. But the whole Facebook system of Apps is geared toward opening up the audience of your private information to third parties, including information you provided under the condition that it is only visible to friends. The privacy policies simply do not have your privacy at heart, and keep changing. You have to keep telling it not to display certain information time and time again every time a new feature gets added.
Sure, if you don’t put the information up in the first place you have nothing to worry about, and it’s debatable as to whether you have anything to worry about anyway, but I just don’t trust a service that keeps moving the goal posts.
