I love IPv6 but organizations seem to struggle with it. My ISP, for example, had issues routing it after a backend update so they decided to just turn it off. I'm now stuck on CGNAT IPv4 which results in constant captchas :/
Meanwhile, there is a whole grey market built around this. People sell “CGNAT mobile proxies” that ride on carrier and ISP NAT, and the whole point is that they are a pain to block without nuking huge ISP ranges. So they get marketed as a convenient way to dodge shadowbans, spam filters, and basically any abuse defense that relies on IP reputation.

What makes them a pain to block? Angry users or some central database that lists these addresses as "do not block"?

Not wanting to cut off access to your users from, for example, every AT&T device (and their MVNOs).
Since cgnat means NATing a huge number of legimate device to a single ip. So angry users is the answer. Also note mobile users are usually the cgnat.
It would be nice if we had a blackout CGNAT day where a bunch of major sites don't serve traffic to people behind CGNAT to give the ISPs a bit of a scare.
This is a win for the consumer though, we don't want to be tracked, your inability for abuse prevention is my ability to stay hidden in the crowd. Why should I care?
