It's Mastercard's world; we just live in it. That's my understanding based on a recent communiqué from Valve to PC Gamer, which confirmed that, yup, the company sure did recently remove a whole spate of adult games from its storefront because it made payment processors upset.

Valve is tightening its guidelines around 'adult only' content to satisfy rules set by Steam's payment processing partners, with dozens of sexually explicit games removed from the platform throughout the week.

Dozens of pornographic games disappeared from international Steam stores. Valve stated a complaint from payment service providers is responsible for this.
