Why did my payment processor fine me thousands for card network rules on products I never sold?
Merchants on Shopify Payments and similar processors get Mastercard BRAM fines passed straight to their balance for listings the network calls unauthorised, with no named rule, no evidence and no real appeal.
Who has it: Small online merchants on Shopify Payments, Stripe or other payment facilitators, especially resellers of software, branded or regulated goods.

A merchant-side catalog scanner that checks every listing against card network brand protection and high-risk rules before the processor's monitor does, and builds an evidence pack when a fine lands.

Lists banned categories in broad terms, no per-listing check.
- Solicitor dispute
Expensive, and processors pass the fine through under their terms anyway.
