I was banned from the hCaptcha accessibility account for not being blind (2023)

Some captchas are getting pretty discriminatory, not everyone lives in the West and can identify the objects they are asking you to. Another recent one sticks out where they asked me to pick a shape as the same number of conoids on screen. If you ask people on a street what a conoids I bet a significant amount will give you blank looks

Also at least now I know some people call those markings crosswalks

I live in "the West" but English isn't my main language. I have no idea what a conoid is.

> A conoid is a ruled surface whose rulings are parallel to a plane (called the directrix plane) and intersect a fixed line (called the axis of the conoid) (Gellert et al. 1989, p. 202). Examples include the circular conoid, helicoid, hyperbolic paraboloid, parabolic conoid, Plücker conoid, right circular conoid, Wallis's conical edge, Whitney umbrella, and Zindler conoid. If the axis is perpendicular to the directrix plane, the conoid is called a right conoid (Gray et al. 2006, p. 436).

so, a surface with stripes - example https://pxhere.com/en/photo/1366651

Where did you get stripes from in any of that? A surface is ruled when it can be constructed by extruding a line (or segment) along some path… like waving a ruler around.
