Anti-Spam Webforms Leave Out The Blind

geekee writes "An article on CNET claims that a technique whereby a user enters a code word displayed in an image in order to register for a service such as an e-mail account discriminates against the blind. Advocacy groups for the blind are even hinting at lawsuits against companies using this practice. A proposed audio workaround for the blind still has problems since it has to be garbled to the point where most people can't understand it to prevent a computer from recognizing the letters. Brings up some interesting issues surrounding the Turing test."
