What you and mijoharas allude to is a cute urban myth. Pornhub never appeared as Pornhub on your bank statements and the same goes for every serious adult content site for decades. And if it was about chargebacks Visa would never even touch Amazon or AliExpress.

Read why Pornhub was ditched in 2020/2022. Trigger alert, it involves rape and trafficking victims.

Or read the sources mijoharas posted. They specifically say that payment processors simply do not like porn. I guess he did not read his own links.

Mijoharas and I both mentioned the adult industry, you've closed the scope down to just pornhub for some reason -- essentially you're arguing some other argument no one else made.

Payment providers note higher chargeback rates for adult/porn services than those for other mundane services, this is a longstanding -- pre-internet, even -- pattern which has nothing to do with the pornhub situation within the last 5 years.
