Paypal is not very cool with nsfw payments, I had an account permanently deactivated with no reason given, and it cannot be appealed.
When emailed, they first insists that they are allowed deactivate my account and they're not obligated to give a reason. After some pushing, the best reason I've got, is that I violated their acceptable use policy.
After some digging, I found that porn/illicit materials is against their policy, and theres one payment from my account to an adult game on itch. That's the only thing I could find that is a violation.
This was just a couple of months ago.
