They literally do this on Roblox, I've seen over 20(!) hard puzzles and about 10 seconds to solve each one: https://devforum.roblox.com/t/impossible-roblox-captcha/3214...

For some challenges, this is so impossible that people give up with logging in until it calms down in a few hours, even Roblox employees and full time developers

People have told me that Arkose pay people to run their captchas and present lots of fancy metrics of attacks they've stopped which is why some websites seem to be ok with destroying user experience by running this

If regular users can't log in, that would decrease the load, and that could be presented in those metrics i suppose.

"Look! there was an artificial traffic spike here... but then our systems kicked in and saved the day!" (By locking out paying users and letting in bots, because that's easier for the 'protection' company and gives the same stats for 'back to normal' in the reports)
