And their thoroughly unhelpful reply:

"Hi there, sorry to hear you're having difficulties!

We have an alternative authentication scheme that you may prefer: https://www.hcaptcha.com/accessibility

You can sign up here: https://dashboard.hcaptcha.com/signup?type=accessibility

This lets you avoid the challenge altogether after registration.

It is designed for users with any kind of difficulty solving the challenges.

Thanks for reaching out, and hope this makes your experience better."
