For instance they block me because I'm behind CGNAT and because some of the millions of machines also behind that CGNAT once did something unsavory.
I'm not a customer of Cloudflare, so I have no one to call, I just get blocked from endless websites or have to click a checkbox, solve puzzles and suffer other indignities because I'm using a reputable and popular ISP in my country.
Fuck Cloudflare. They're accelerating the utter shittiness of the web because of their indiscriminate solutions to web malfeasance, which are worse than the disease.
