i personally find captchas tiresome, i have a very effective method for spam control. I alwayz include a hidden field in a form i need to protect frm spam, bots will always set values for all the fields in the form, so i just check, if(isset(my hidden field)) { u must be a bot coz no human would fill a hidden field } else { u must be human } } On Wed, Sep 16, 2009 at 8:25 PM, saidimu apale <saidimu@gmail.com> wrote:
What is unique about reCAPTCHA, and I suppose why Google were interested, is that it provides you with security as you help "proof-read" OCRed (optical character recognition) books. Very clever!
