You don't have to have everything linked. Google, Fakebook, and the other big tech companies are all concluding to build a profile on you, and that includes your spending, friends, shopping habits. Everything!

I use Amazon from time to time, and now the SOBs know it's me without even logging on. How? They have a profile saying this is my computer, and most likely it is through cookies or some more insidious methods that they know it. The right to privacy has completely died in the USA and the world. It needs to be brought back and those abusing it brought down.
