Wil, I feel it for you. As a person who has made most of my living from copyrighted material, and generously donated as much as I possibly could to the "copy this for free" sphere, I'm particularly annoyed when the few things I've done that require no copying be, well, uh, copied. Good luck with outing this guy. Maybe you just need to find better retaliation means. :)
