> customer defaulting after using a merchant's service

I think the defaulting rate would just get baked into the asking price. But I'm assuming there isn't a way to repeatedly systematically default to get unlimited free content.

Each customer already has a limit on the amount they can owe before we require payment. Each customer account also requires a unique payment method, which must pass Stripe Radar and 3-D Secure checks. We plan to add more checks in the future.
