From the article:
It can be very frustrating when you have a form on your site which has a good and useful purpose, but almost becomes obsolete because of relentless spamming. I had this problem a few months ago with my old site, and was thus forced to find a solution that was light-weight, easy to implement, and most importantly was effective. I decided to turn toward my friend CSS to help me out.
Keep in mind that implementations like the ones mentioned above cannot stop trackback/pingback spam.
