Does 4Chan also have bot BEHAVIOR detection (e.g. unnatural mouse movements)that google captcha has?

It does not, at least not once you pass the Cloudflare Turnstile challenge (which can be done with an API as well.)

The results here suggest it does not.

Yeah I had been under the impression that the point of captchas like this (and those "slide a puzzle piece" ones) weren't the solution to the problem as much as checking for human-like mouse movements.
