It seems like stripe is the only supported payment provider. Generally Patreon and similar services serve as a policy intermediary to the payment providers, and the platform policies are usually driven by payment provider policies against offensive content which the payment provider opposes or other categories at high risk of payments fraud. Platforms such as Patreon and OnlyFans serve as collective bargaining tools due to platform scale and fraud management, allowing users to sell content they would not be able to sell on their own site without being suspended by e.g. PayPal or Stripe.

How can Pinepage prevent Stripe from suspending users?
