Well, It is a frightening thought. However, I really don't mind who knows what about me. I am a completely open book. If people email me that I don't want to email me I can block them. If people telephone me when I don't want them telephoning me I can block the number. I can pretty much block annoying people anywhere and, lets face it as far as the authorities are concered they don't need to look at facebook to track you. If you use the internet, telephone, or any other mass media you're screwed. There is no such thing as privacy.
