1000% I got legit Cloudflare Workers Anycast IPs that I was using for websockets blocked.
I also got blocked from using RustDesk.
It's been crazy. As this happens intermittently. I had to set up a tailscale exit node in one of my servers to circumvent this crap. I lost several days and called Vodafone (ISP) to understand what was going on.
That's when I read Reddit and saw that crap.
I’m suprised no one has sued over it, some sort of class action.
I don't think RustDesk was hit by this. If you weren't able to access it two weeks ago, it was due to an outage on their end: https://github.com/rustdesk/uptime/issues/53
