Actually DoubleClick does know name and other info on most people. Ever fill out a form on a page with a DoubleClick ad on the top? Guess what? Their cookie with your ID goes to the company you filled the form out to asks you if they can share your info with their providers who are interested in selling their products to you. Guess who is their provider for all that other stuff. DoubleClick.. They then connect the DoubleClick database to their database and DoubleClick now know's your info. There was that lawsuit about DoubleClick doing this (which I think they won) and the lawyer was able to get his name, SSN, address, phone number, and other info from the DoubleClick database.
