Spam-X is a small anti-spam program that seeks to block +email harvesting spambots and flood them with hundreds or even thousands of worthless e-mail addresses. It "hides" these junk mailto: links in the body of a normal-appearing HTML page, which it generates using words from a dictionary of over 45,000 English words. It generates each page of junk mailto: links very slowly, thereby wasting the spambot's time. Last but not least, it includes a "loop back" link to itself, with a random parameter, hoping to fool the spambot in to endlessly looping and thereby getting "stuck" on the Spam-X link and blocking it from ever reaching your real email address.
