Anubis screws with me a lot, and often doesn't work.
There’s literally no way for you to bypass the block if you’re affected.
Its incredibly scary, I once had a bad useragent (without knowing it) and half the internet went offline, I couldn’t even access documentation or my email providers site, and there was no contact information or debugging information to help me resolve it: just a big middle finger for half the internet.
I haven’t had issues with any sites using Anubis (yet), but I suspect there are ways to verify that you’re a human if your browser fails the automatic check at least.
Anubis looks much better than this.
The Soccer rightsholders - LaLiga - claim more than 50% of pirate IPs illegally distributing its content are protected by Cloudflare. Many were using an application called DuckVision to facilitate this streaming.
Telefónica, the ISP, upon realizing they couldn’t directly block DuckVision’s IP or identify its users, decided on a drastic solution: blocking entire IP ranges belonging to Cloudflare, which continues to affect a huge number of services that had nothing to do with soccer piracy.

Basically we're already past the point where the web is made for actual humans, now it's made for bots.
It has, scrapers are out of control. Anubis and its ilk are a desperate measure, and some fallout is expected. And you don't get to dictate how a non-commercial site tries to avoid throttling and/or bandwidth overage bills.
Unless you're paying Cloudflare a LOT of money, you won't get to talk with anyone who can or will do anything about issues. They know about their issues and simply don't care.
If you don't mind taking a few minutes, perhaps put some details about your setup in a bug report?
(Not to mention all the sites which started putting country restrictions in on their generally useful instruction articles etc — argh)
You might have to show a passport when you enter France, and have your baggage and person (intrusively) scanned if you fly there, for much the same reason.
People, some of them in positions of government in some nation states want to cause harm to the services of other states. Cloudflare was probably the easiest tradeoff for balancing security of the service with accessibility and cost to the French/Parisian taxpayer.
Not that I'm happy about any of this, but I can understand it.
It is easy to pass the challange, but it isn't any better than Anubis.
If you fall in the other 1% (e.g. due to using unusual browsers or specific IP ranges), cloudflare tends to be much worse
We should repeat this until every network is cloudflared and everyone hates cloudflare and cloudflare loses all its customers and goes bankrupt. The internet would be better for it.
The article doesn't say and I constantly get the most difficult Google captchas, cloudflare block pages saying "having trouble?" (which is a link to submit a ticket that seems to land in /dev/null), IP blocks because user agent spoofing, errors "unsupported browser" when I don't do user agent spoofing... the only anti-bot thing that reliably works on all my clients is Anubis. I'm really wondering what kinds of false positives you think Anubis has, since (as far as I can tell) it's a completely open and deterministic algorithm that just lets you in if you solve the challenge, and as the author of the article demonstrated with some C code (if you don't want to run the included JavaScript that does it for you), that works even if you are a bot. And afaik that's the point: no heuristics and false positives but a straight game of costs; making bad scraping behavior simply cost more than implementing caching correctly or using commoncrawl
As a legitimate open source developer and contributor to buildroot, I've had no recourse besides trying other browsers, networks, and machines, and it's triggered on several combinations.
Thinking about it logically, putting some "serious" banner there would just make everything a bit more grey and boring and would make no functional difference. So why is it disliked so much?
But at the end of the day both are shit and we should not accept either. That includes not using one as an excuse for the other.
Also, Anubis does have a non-JS mode: the HTML header meta-refresh based challenge. It's just that the type of people who use Cloudflare or Anubis almost always just deploy the default (mostly broken) configs that block as many human people as bots. And they never realize it because they only measure such things with javascript.
I dislike those even more.
