What happens when self-organizing systems are perturbed? Compensatory perturbations, like the fact that the do-not-call list will shift direct marketing to spam, junk mail, and other schemes to reach you, like this:

�...The FTC has said that the do-not-call provisions do not apply to �up-sells.� That is the basis of the inQ program,� inQ counsel Linda Goldstein said".

Or the far, far worse:

"...SBC Communications Inc., for instance, has started in recent months to send salesmen door to door, according to spokesman Michael Coe".

It's an arms race. They'll find a way to reach you, because in the end, people buy things from direct marketers. According to the DMA, it's a 100 billion + dollar industry. Even if we halve that number, because the DMA aren't exactly trustworthy, that's still a hell of a lot of money waiting to be found by cheesy marketers.
