A CSS trap for comment spambots
Kudos to the person who thought about this! This article describes how you can prevent comment spam with CSS. I am not sure how well this performs, but it sure looks like a decent solution. I would like to test if it would perform better than my trick of dynamically changing the form field names with Javascript, which I use in the comment-policy plugin for WordPress, but I guess I’ll leave this for some other time, as I currently try to move as far away from WordPress comments and trackbacks as possible.
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.
An example can be found here.
Keep in mind that implementations like the ones mentioned above cannot stop trackback/pingback spam.
