More Spam-Fighting Tools

There's something more to ReCAPTCHA that I'd like to mention. ReCAPTCHA is also a program that digitizes old books, and the words that the digitizing computer is unable to recognize are sent out as humanity tests.

So if you use ReCAPTCHA you're not just fighting spam, yuo're preserving literature. ( http://recaptcha.net/learnmore.html )

Another handy anti-spam tool for your website is Spampoison. All you have to do is put link (not necessarily a visible one either) on a page that gets traffic from spam bots. The bots follow the link which goes to infinite loop of randomly generated garbage e-mail addresses. ( http://www.spampoison.com )
