I've yet to be banned by cloudflare but they will sometimes harass me with challenges that require JS to run.
Usually that's just an annoyance, but I often have to investigate questionable and outright malicious websites for work and some of them have started to use cloudflare so that you're forced to allow JS for the evil domain just to get past cloudflare's checks before you can even see the harmful website which then wants to use JS against you. Cloudflare is an affront to the philosophy of the internet and a menace.
