How to Prevent Form Spam Without Captchas

Posted by ryuzaki0 on from the can't-beat-the-curte-power-of-kittenauth dept.

UnderAttack writes "Spam submitted to web contact forms and forums continues to be a huge problem. The standard way out is the use of captchas. However, captchas can be hard to read even for humans. And if implemented wrong, they will be read by the bots. The SANS Internet Storm Center covers a nice set of alternatives to captchas. For example, the use of style sheets to hide certain form fields from humans, but make them 'attractive' to bots. The idea of these methods is to increase the work a spammer has to do to spam the form without inconveniencing regular users."

    Perhaps the vision impaired should just learn to live withing their disabilites and accept the fact that not everything is going to be availiable to them. Harsh, yes but its life. Making resonable requests to accomidate them is one thing but making people liable under law for not is something else.

    Please don't continue the "USian" meme. It's confusing the citizens of the United States of Mexico. Thanks!

    So that's why you guys can't stay on your side of the border.
