The whole purpose of MAPS is the Balkanization of the internet. Balkanization of the Internet is a good thing. There should be parts of the Internet that are spam-free (that's where I want to be) and other parts where peoples' mailboxes are constantly full of get-rich-quick-find-out-anything-about-snow-white-and-the-seven-dwarves-penis-enlargement-offers. People who want that kind of mail should get it, and those who don't shouldn't.
