On the one hand, as a person without vision problems, I find captchas annoying anyway. I can image that those with vision problems find they are a complete blockade to participation.
On the other hand unfettered spam in website comments destroys the value of the site and comments completely.
So, what alternatives are there to captcha that allow the sight impared to participate while still hindering spam-bots?

Download Linux

Other options?
