My formulation is: big brother isn't watching, he's outsourcing.

While many of these services don't advertise an opt-out mechanism, there's nothing to stop you from writing them publicly to request an opt-out. Or visiting them in person (a team of imric, myself, and the Gryg brings a certain warmth to my heart). Or send a cease and desist letter. Or send one via an attorney. Or mail your local/state/national district attorney / attorney general, copied the firm.

I can assure you there are a number of people living in heavily coveted marketing zones who are highly effective at keeping their personal information just that -- personal. Their means for doing so is not unattainable to you or anyone else here

As a friend remarked last night: geeks tend to be awfully literally minded. We are used to a set of instructions, so long as legally formulated, to be processed by the computer. If we got a "go to hell" response we'd be quite surprised. This is a perfectly valid response to a legal or business challenge, howeever.
