A Preliminary FTC Staff Report on "Protecting Consumer Privacy in an Era of Rapid Change: A Proposed Framework for Businesses and Policymakers"
I believe that the proposed do-not-track mechanism is a bad idea because it implies that tracking is acceptable in the absence of specific declaration. Instead, you should standardise a please-track-me mechanism, for people wishing to be tracked. The mechanism may include a client-generated unique id number to make tracking even easier for the parties the client has chosen to allow. Once this mechanism is widely avaliable to consumers, any tracking performed in the absence of the please-track-me token may be made punishible by fine.
