CAPTCHA is an acronym for

Completely Automated Public Turing test to tell Computers and Humans Apart

I think most sites would be open to a suggestion. But it is not known
how to solve the problem.

The problem is that spammers target websites that perform automated
comment-posts or automated sign-ups.
Their programs post all kinds of nonsense comments or articles, often
with links to irrelevant sites that they operate.
(I'm sorry I couldn't find an example victim site for you)

Websites of course want ordinary people to contribute or sign-up, but
how does one recognize and block spammers?
The ordinary CAPTCHA's you mention kind of work for sighted people,
but not that well either.

How to allow the blind to participate while preventing spammers? If
you have an idea, feel free to let me know (or this list)
