Comment Re:Visa/Mastercard are not payment processors (Score 1) 245
I have not worked for a payment processor, but I've implemented service connections to many over the last 20 years. Visa/MC absolutely have rules, and they will suspend payment processors for collecting money in violation of them. Example. Another example, if you still don't believe me. The processors would love to collect money for everything. The reason you're not seeing platforms switch to different processors, is because the rules come from above. Do more research, and recompute your position.
Of course they have rules! But, some of the payment processors have far more draconian rules.
The two docs you link from MC list requirements like: "not illegal", age verification of (real-life) people depicted, age verification of uploaders, and an appeals process for people to get their pics removed. (The rules are generic, not specific to game sellers.)
Compare that to the paypment processors. Itch.io uses PayPal, Stripe, and Payoneer. The Payoneer published requirements disallow quote "games that include pornographic or mature audience content"! Stripe's requirements include similar wording.
Visa/MC are indeed a problem. But, some of the payment processors are far worse than MC/Visa. And, itch.io needs to go shopping for less restrictive payment processors.
