Про CAPTCHA
Любопытный факт:
"...
Human solvers
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.
