I'm a NSFW game developer. What many people may or may not realize is that all the current payment processing options available for developers to take payouts with (PayPal, Stripe, and Payoneer) ALL have policies banning the use of their services for the exchange of adult content.
To adhere to their policies, I'm currently giving away my game for free, with the option to donate to me personally via the 'Pay What You Want' option at time of download. The current UI prompt does indicate that "This game is free but the developer accepts your support by letting you pay what you think is fair for the game.", but I worry that the language "letting you pay what you think is fair for the game" could be misinterpreted by some payment providers as the users still paying for the adult content.
It would be nice if this language could be made more neutral, in general or specifically in the case of NSFW games, because of the delicate nature of monetization and adult content to separate this donation from payment for the game itself.
Perhaps something along the lines of "This game is free but the developer accepts your support in the form of an optional donation." or something of that nature?
