The website are not part of the game at all.  It's much simpler.

Spammers would like to solve CAPTCHAs.  They submit them to the hypothetical
CAPTCHA solving service, with micropayment, and receive the solution.
Outsourcing through the Tor network would make it possible in real time.

It's just a thought experiment.  Ever since we've been subjected to this
nuissance I've had the opinion that services like Cloudflare (not to pick
on them) that centralize the web are harmful.
