Oh, yeah, and if you block cloudflare.com third party JS and whatnot, guess what? that doesn't work! it just displays a vaguely patronizing error message.

(It used to just say "unblock challenges.cloudflare.com to proceed" which was significantly less offensive, IMO. Treated you like a person who knows what you're doing, which you are if you've decided to manually block cloudflare.com, and tells you what the exact domain at issue is if you feel like giving in.)
