Facebook sued for tracking users, even after they logged out

Hundreds of millions of people use Facebook and like (and love) it, but the regular stream of privacy problems encouraged me to delete my account years ago. As the financial pressure on Facebook to hit quarterly and annual numbers increases, this is likely to get worse than it already is today.
Privacy matters:

Facebook is being sued for $15 billion for tracking users, even after they have logged out of the social network, and violating federal wiretap laws. If that sounds familiar, that’s because it is: Facebook faces nationwide class action tracking cookie lawsuit.

Today’s lawsuit, filed in Federal Court in San Jose, California, combines 21 separate cases across the U.S. in 2011 and early 2012. It’s an amended consolidated class-action complaint that claims the company is invading the privacy of its users by tracking them across the Internet. If the claimants are successful in their case against Facebook, they could prevent Menlo Park from collecting the huge amount of data it collects about its users to serve ads back to them.
