The "solution" is to shoot CGNAT and to finally force the ISPs to adopt IPv6 so everybody can drop the addresses of a detected residential proxy into a ban list.

Continuing to allow CGNAT is what allows the residential proxies to hide because it tumbles the IP identity of bad actors with normal people.

Your premise seems to be that you expect IPv6 addresses to be scarce.

Tell us that you don't know how residential proxies work, without telling us that you don't know how residential proxies work.

No, they are correct, residential proxies behind a big ISP's CGNAT is much more valuable for miscreants because you can't block the individual who installed a free android flashlight with a residential proxy SDK embedded.
