Of course their challenge requires those things. How else could they implement it? Most users will never be presented with a challenge though and it is trivial to disable if you don’t want to ever challenge anyone. I was just saying CF blocks ML crawlers.

Huh? I can reach my site via curl that has neither. How did you come up with this random set of requirements?

I’m not sure how they actually implemented it, but you can easily block ML crawlers via cloud flare. Isn’t just about every small site/service behind CF anyway?

This project dead?
