JZ: CAPTCHA is evil! Image CAPTCHAs are not accessible for visually
impaired. Audio CAPTCHAS are not accessible for deaf. Both are not
accessible for deafblind.
Audio CAPTCHA isn't solution, because it's made for english native
speakers. What could you do if somebody offer you audio CAPTCHA in
Polish or Chinese? Image CAPTCHA uses roman letters, but what about
people using another alphabets, for example CJK or arabian?
Accessible pages shouldn't use CAPTCHAs, because they're not compliant
with WCAG 2.0
