Also a great way to block the access to people that do not have a payment system available. Whether it is because they are not in a country that's well integrated into an international payment system, or because they are under 18.

I browsed a lot of those sites when I was a teenager and did not have a credit card or easy access to internet money.

Aren't many of those countries basically being de-facto blocked by Cloudflare filtering out spam already anyways?

Genuine question, I'm not up to date on how Cloudflare operates right now
