why people keep suggesting using a messed up image to check if people are real or bots?


What about the people that can't see well? I mean, we have accessibility guidelines suggesting we put an alt text on every image and then we cut out from a service all the blind and visually impaired people?


PS
I think reusing the same file at every access causes a classical race condition, but I may be wrong..
