Summary0008129: Alternative to captchas
Description

Captchas are bad for accessibility:
http://www.w3.org/TR/turingtest/
http://www.w3.org/2004/Talks/0319-csun-m3m/slide1-0.html

There's no way one can sign up for an account with captcha's enabled if one is either blind or uses a text-only browser.

Please consider implementing an alternative Turing test. E.g. questions of the type 'what is 5 add eight' checking against numeric answer, etc.

TagsNo tags attached.
