What a paranoid miserable way to live your life. You are tracked with everything from Supermarket Loyalty cards to street CCTV anyway. People use social media for a myriad reasons, form organising events to keeping up with family and friends around the world. The hilarity of getting on your soapbox on a forum in which I would not be surprised if you videoed your arse on is not lost on me. It's also strange considering that you insist on using your own face in your signature. Chill out man.
