Captchas are quite simple

You just look at them and read the letters. This proves you're not a robot...  Try the ones above.

And why doesn't this surprise me:
"CAPTCHA is vulnerable to a relay attack that uses humans to solve the puzzles. One approach involves relaying the puzzles to a group of human operators who can solve CAPTCHAs. In this scheme, a computer fills out a form and when it reaches a CAPTCHA, it gives the CAPTCHA to the human operator to solve.

Spammers pay about $0.80 to $1.20 for each 1,000 solved captchas to companies employing human solvers in Bangladesh, China and India..."

    I've read that some captcha relay schemes just use strip-tease as a way to get this info for free.
