Spoiler alert: many websites simply refuse to load at all (e.g. any google service, and lots of websites "protected" by CF). Captchas are everywhere: in many cases, you can't even complete simple GETs of blogs without donating free labor to CF.
And the most infuriating part, you get CF marketing messages right in your face while your browser is calculating hashcash (I guess?)... At this point I can recognize every single one of them: something about bots making up 40% of all internet traffic, something about their web scraper protection racket, something about small businesses (???), etc etc...
To be fair, Tor exit nodes have an awful reputation for sure. Nevertheless, I have a hard time forgiving how CF makes browsing the Internet hell for those who actually need Tor.
