Well, the Detroit Free Press has a very interesting article on him. This guy is about as unrepentant as they come, and he's saying he wants to branch out into delivering pop-up spam via the Windows Messanging service present on most Windows boxes. If you sysadmins out there have been wavering about whether to block spam-friendly networks, read this article, then go to The Spamhaus Project and SPEWS and start getting IP ranges to block."
