There are much better ways of rate limiting that don't steal labor from people.
hCaptcha, Microsoft CAPTCHA all do the same. Can you give example of some that can't easily be overcome just by better compute hardware?
The problem is the unethical use of software that does not do what it claims and instead uses end users for free labor. The solution is not to use it. For rate limiting a proxy/load-balancer like HAProxy will accomplish the task easily. Ex:
https://www.haproxy.com/blog/haproxy-forwards-over-2-million-http-requests-per-second-on-a-single-aws-arm-instance
https://www.haproxy.com/blog/four-examples-of-haproxy-rate-limiting
And what will you do if a person in a CGNAT is DoSing/scraping your site while you want others to access? IP based limiting isn't very useful, both ways.
HAProxy also has stick tables, pretty beefy ACLs, Lua support, and support for calling external programs. With the first two one can do pretty decent, IP, behavior, and header based throttling, blocking or tarpitting. Add in Lua and external program support and you can do some pretty advanced and high-performance bot detection in your language of choice. All in the FOSS version, which also includes active backend health checks.
It's really a pretty awesome LB/Proxy.
