> It is, however worth at least considering restrictions on continuously following a person in public places and reporting all their observed activities to a third party.

I don’t see any difference between online “tracking” and real world stalking. If some one was following you every where you went taking notes on everything you did, interrupting you and preventing you from actually doing what your were actually wanting to do, you’d be able to have the police intercede in your behalf. Only now we think it is different because “on a computer”.???
