my understanding is Google's recaptcha has been doing this sort of thing forever, tracking mouse movements (as well as browser fingerprinting, IP address, and probably a million other tracking methods) to score a client as more or less likely to be human, and it's only when it's suspicious that it escalates to "pick the images that contain x"
I always thought the pick the images was just an excuse to get training data because it’s never “choose images that contain a bear frolicking in a meadow” it’s always “choose images of motorcycles, busses” or “locate the Abram’s tank hidden in the tree line”.
This has always been the way captchas work, I guess they're expanding it to be always-on.

This made me laugh out loud.
"Click or tap on all pictures of ARMED INSURGENTS TAKING COVER IN RUINED BUILDINGS until no more are left."
"follow the man with your mouse cursor until the light flashes" will be the next step in crowd sourcing for the army...
Por que no los dos?
They do that as well, but its so annoying they probably just hold it back unless extra verification is needed.
