Best unobtrusive anti-spam technique (Not CAPTCHA) | Urbano's Blog - 0 views

    I know you are probably thinking that this will be some silly thing, but this idea that Thomas Landauer came up with is by far the best I've seen in a long time. Add CSS-hidden fields that a user won't see, but a spam-bot will fill. Then using php check if they were filled, and if they were: block the spammer!
