But seriously, aren't there any bright anti-spammers who could just take down this guy's servers? Can't a small army of anti-spam hackers just track the mail headers back to the sending servers and take those servers down? It could be a counter-spam hacking movement. I mean, all these hackers are so busy writing viruses to see which can score higher on Symantec's Security Report, why not write viruses to toast spam friendly ISPs?

Um, you should not fight abuse with abuse. Do the right thing -- report the spammer to his/her ISP and have the account terminated. If the ISP is spammer friendly, learn to add them to your blocklists.
