Hey guys I was wondering how you guys use CAPTCHA... I mean... I know how to code a basic one but I was wondering about the content you put into the image. Meaning, I've started to get bots who can read the code so I've started to make the CAPTCHA codes basic math problems. Do you guys think that any other content in CAPTCHA is annoying or have you found better ways to preclude bots from reading them.
By the way, I keep track of CAPTCHA failures so I know if a bot is trying to guess it... Funny when I see it says "13+14" instead of 27.
