It's irrelevant if you worked on the team. Facebook is a profiling tool. Its users have traded their privacy for convenience. Please tell me that Facebook doesn't track people using the Facebook banners/IP address combinations... or better yet, tell me that Facebook isn't the ONLY one that does it as a justification for selling people's personal data.

Facebook is only worth 100bn because it sells peoples' personal information.

Am I jaded? Not at all. I am a realist. Facebook is primarily a monitoring tool that monetises itself on selling people's personal information.
