I'm sorry for you. The problem is with the content provider, and i'm just as annoyed/angered as you are by this. I routinely send "complaint" emails to websites to let them know they're actively blocking users, because usually they don't even know that and they assume cloudflare & others are just blocking malicious traffic. The more complaints they receive, the more inclined they'll be to let us through.
