[ANTI-SPAM] - Why do spammers forge someone's domain name and use that domain to send their spam? It's a good way to cover their tracks. But what happens if the person who owns the domain name finds out? What happens when he is a security expert and hacks into the spammer's computer?

Chuck sent me a link to such a story a couple of weeks ago. The original link is dead, but this site contains links to some mirror sites where the hacker documents all of the spammer's activities. It's some interesting reading: Behind Enemy Lines. (Warning: the domain name hosting this page uses profanity in its name).
