		jat850 on March 18, 2014 \| parent \| context \| favorite \| on: I can no longer solve ReCAPTHCA captchas I played around with it for a while. It seems invalid attempts add another required item to the captcha queue. So if you are trying to solve the first one, and fail, it adds another one that the bot must attempt. I am not sure if this helps much, but it was noteworthy.

Botnetters have thousands of IP addresses to attack from. They can also use successful attempts to build a database of images used by this CAPTCHA
