I've seen your feedback request for the Inaccessibility of CAPTCHA Working Draft, and I'd like to share what I have learned about the reCAPTCHA service while I was working on Buster.
The most prominent issue is that reCAPTCHA selectively blocks the audio challenge, while the visual challenge remains available for solving. This practice discriminates against people with visual disabilities, and blocks them from getting access to services and information on the web.
The reCAPTCHA Google Group and other forums have several threads about people with disabilities looking for a solution because of the blocked audio challenge, this is one of them: https://groups.google.com/forum/#!topic/recaptcha/5TFQ2c4phPU/discussion
https://groups.google.com/forum/?nomobile=true#!searchin/recaptcha/audio%7Csort:date https://www.google.com/search?q=%22audio%22+%22captcha%22+OR+%22recaptcha%22+%22automated+queries%22
This is the message people are encountered with when they try to access the audio challenge: Your computer or network may be sending automated queries. To protect our users, we can't process your request right now.
This happens because the reCAPTCHA algorithm erronously flags real people as bots, and it simply blocks access to the audio challenge instead of offering a challenge that is harder to solve.
The blocking of the reCAPTCHA audio challenge is a regular occurence while browsing the web from residential IP addresses. People have reported some level of success in accessing the audio challenge by switching to Chrome and staying always logged into their Google accounts.
The reCAPTCHA service is also hostile to users connecting from VPNs or anonymizing services such as Tor. The audio challenge is almost always blocked when using Tor, and the visual challenge may be blocked as well, or serves several challenges in a row and refuses to accept correct solutions.
Because of the dominance of the reCAPTCHA service, people seeking privacy are effectively prevented from accessing large portions of the web.
