I think it's safe to say that blind AND deaf people surfing with

When you target this disabilities group, I guess you have to take the
risk of spamming and NOT use CAPTCHA.
This isn't just a blind-and-deaf issue. I fail about 10% of captchas I
encounter... at some point they get to the point that they are so good
against computer vision that they surpass what my HUMAN VISION is
capable of. Forms should not involve extra work for users... that's
guilty before proven innocent. Forms should identify and catch bots
while letting humans enjoy a work-free experience; I responded to the
original post in this thread off-list because I figured it was OT, but
I'll post the recommendations I made:
- tying into Akismet: http://akismet.com/ which gets better everyday.
- using honeypots and hashes:
http://www.nedbatchelder.com/text/stopbots.html which is FAR more
accessible than CAPTCHAs or random questions.
Anyway, I posted on this issue recently (before this thread, actually)
and I'm not trying to advertise or anything, but you can read what I
