I know that the mastodon team are suggesting you turn on #hCaptcha for signups to your instance, to combat the spam wave provided by a rudimentary script that doesn't have the smarts to get around it.

I vaguely remember, however, that people have previously raised #accessibility concerns about it. Does anyone have any experience with the accessibility or lack there of, of signing up to instances that use this feature?

If it is indeed inaccessible, I don't consider this to be a reasonable solution.


So I wrote a blog post for the first time in 5 years, warning about hcaptcha's accessibility account. Long story short, they banned me from the accessibility account because I'm not blind. I am blind, but well, they seem to think not. Please boost, share, etc since this seriously affects me, and it's not ok at all. You can read the full blog post here: https://4mt.me/hcaptchastory

Please, please do not do this under any circumstance, if you care about your instance being accessible to the #blind and visually impaired (hint, you should).

#HCaptcha is a horrible example of how not to implement a #captcha solution, forcing people to register their email address and store a cookie, as well as disable cross origin restrictions on their devices in order to pass validation.

There are much better alternatives, such as the no-hassle https://github.com/mCaptcha/mCaptcha, which does not need any user input other than checking a checkbox. Alternatively, use captchas that provide text versions, e.g. via solving a math question or at the very minimum, provide an audio version, knowing that it is not ideal for the hearing impaired.

HCaptcha is NOT the future. #accessibility #a11y
