> These Captchas are really bad at detecting bots and really good at falsely labelling humans as bots.
As a human it feels that way to you. I suspect their false-positive rate is very low.
Of course, you may well be right that you get pinged more because of your style of browsing, which sux.
source: I work in a team that uses this kind of bot detection and yes, it works. And yes we do our best to keep false positives down
Back when I was playing Call of Duty 4, I got routinely accused of cheating because some people didn't think it was possible to click the mouse button as fast as I did.
To them it looked like I had some auto-trigger bot or Xbox controller.
I did in fact just have a good mouse and a quick finger.
If CloudFlare mislabels you as a bot, however, you may be unable to access medical services, or your bank account, or unable to check in for a flight, stuff like that. Actual important things.
So yes, I think it's not unreasonable to expect more from CF. The fact that some humans are routinely mischaracterized as bots should be a blocker level issue.
I've never failed the CF bot test so don't know how that feels. Though I have managed to get to level 8 or 9 on Google's ReCaptcha in recent times, and actually given up a couple of times.
Though my point was just it's gonna boil down to a duck test, so if you walk like a duck and quack like a duck, CF might just think you're a duck.
