Apart from the mouse thing (which I'm skeptical about), cloudflare also correlates your traffic with other sites hosted on cloudflare. Bots typically don't visit many sites, click around there, find another one, etc, whereas humans will have visited other sites, will be slower at clicking the button, will have left comments on some sites.

A side to this is that certain techniques will be deliberately obfuscated or simply omitted as a security measure in the hopes of slowing a bad actor’s eventual bypassing of the measure. It’s an arms race and if the intruder doesn’t know what all the locks even are, it takes longer to break or pick them.

It's actually detecting you using emotion and aging. That's the real test...

some of them are also less bot detection and more spam limiting and mitigation. cloudflare's has more stuff built in I'm sure, but things like mCapcha are just proof of work, so if you're trying to make a bunch of accounts or whatever, it's really computationally expensive.

This all humans will be good for in the future, until they atrophy and become a mere appendage of machinegod.

those will fail anyway on a few sites I've gone to. No idea why and sometimes months later it will work for a random interval of time.
