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.
Yeah and the worst part is it doesn't fucking work for the one thing it's supposed to do.
The only thing it does is stop the stupidest low effort scrapers and forces the good ones to use a browser.
Recaptcha v2 does way more than check if the box was checked.

you're not wrong, but it also allows more than 99.8% of the bot traffic through too on text challenges. Its like the TSA of website security. Its mostly there to keep the user busy while cloudflare places itself in a man in the middle of your encrypted connection to a third party. The only difference between cloudflare and a malicious attacker is cloudflares stated intention not to be evil. With that and 3 dollars I can buy myself a single hard shell taco from tacobell.
