they cant get their ai to check a box that says "I am not a robot"? I'd think thatd be a first year comp sci student level task. And robots.txt files were basically always voluntary compliance anyway.
Cloudflare actually fully fingerprints your browser and even sells that data. Thats your IP, TLS, operating system, full browser environment, installed extensions, GPU capabilities etc. It's all tracked before the box even shows up, in fact the box is there to give the runtime more time to fingerprint you.
Recaptcha v2 does way more than check if the box was checked.
