Why don't you create another secure site for adult games?   It could be paid for with cryptocurrency, and other things...

I do hope someone with an enterprising sense and the necessary resources is taking note of the market niche opening up.

I agree that itch.io should build another site specifically for adult games. That’s one solid way to put an end to the constant chaos that comes with the site shadow-banning adult games that break their so-called Terms and Service. It sounds like a win-win situation for the site and the adult game developers.
