Don't know if it'll work and can't be bothered to read the link to find out how it works, but since I'm absolutely plagued by spam, here's a spambot stopper.
Says them: "Help us stop spam by adding a link to this page from your website. It can catch spam bots into a circle that generates millions of false e-mail addresses. Just add a link to http://www.anti-leech.com/spam/spambot_stopper.php"
Done. Just following orders, guv, and hoping for the best.
