comment Accessibility and CAPTCHAs
@iivel, you may notice that in the question I do mention specifically reCAPTCHA and ask if it is a good way to provide accessibility, if it (or some similar solution) is supported on all browsers and usable by all users with disabilities, and so on. Any insight into that would be very welcome!

comment Accessibility and CAPTCHAs
That's not suitable against the threat model I'm working with. In my situation, the CAPTCHA is being used as a low-cost way to deter attacks that are crafted to target a specific site. I want to deter automated guessing and other large-scale attacks against that site. "Tick the n-th box" is too easy to script up an attack on (for one thing, the number of boxes will be so small that random guessing will succeed with high probability). All I can say is, I did diligently investigate the alternatives, and I do have reasons for saying I want to use a CAPTCHA (and make it accessible).

comment Accessibility and CAPTCHAs
+1, as it may be useful to other visitors -- but as I explained in my response to Polynomial, this does not actually answer my question. I did investigate these sorts of alternatives, and I really do need to use a CAPTCHA, not one of these alternatives. I'm not asking for alternatives to CAPTCHAs; I'm asking about accessibility if I do need to use a CAPTCHA.

comment Accessibility and CAPTCHAs
P.S. To put it another way, you didn't actually answer the question. :-) In my situation, a dummy form field does not meet the same security needs as a CAPTCHA. So, I'm still interested in what I should do for accessibility, in situations where a CAPTCHA is needed (for whatever reason). (Nonetheless, +1, as your suggestion might be useful to others who stumble across this page!)

comment Accessibility and CAPTCHAs
I think saying "CAPTCHAs are dead" is too simplistic. There are situations where they do add value. Your proposal helps against mass attacks (the attackers are spammers who are trying to post spam on a million blogs); for that, you don't have to outrun the bear, you just have to outrun the other victims. However, in my case I'm concerned with targeted attacks that focus on a single valuable site (e.g., the attackers want to create a million accounts on that one site). Your proposal doesn't help with that. So, while I like your answer for many use cases, it doesn't solve my particular problem.
