Neat script! I use a browser extension to the same end.
I agree with the author that I'd try contacting the worst offenders first. Mostly out of curiosity as to what would then happen. My guess would be that, if you're actually able to connect with them, the majority would cooperate. I like to live by a kind version of Hanlon's razor.
Though, this now becomes an annual bit of spring cleaning to do, so while I'm ignorant as to why Cloudflare should be avoided, I suppose I would also then try to find a CDN to host the script for people. Either that or teach people to fish by taking down the hotlink-able script entirely.
