Using electronic information about you is using electronic information about you - it is what happens.
If you are on the net, and post something, write something, make a purchase, your info. is there to be swept up. I make a purchase, and for the next number of days, when I click on different websites, I see a picture of what I bought. The store connects to my name and they follow me around the net.
In this electronic age, I doubt you could hide your existence even in a cave you dug in a totally uninhabited jungle. Before you go into the cave, stomp on your phone, take it totally apart, burn it, blow it up, bury some little pieces and drown other little pieces. By morning, there will be a reporter at your cave, asking why you destroyed your phone. A satellite took pictures of your doing that and sent the image to every news outlet in the world.
We are surrounded.
