I would assume that itch.io would provide refunds to those who can prove that they no longer have access.
Viewing post in Refunds for those that purchased nsfw games?
Yeah, I don't trust a company not to try and force the refunds back on the creators. When the games were sold, they were allowed to be on the site. If they decide that a game should be removed retroactively due to a change in the rules, the financial hit for all the refunds should not come from the creators. But we know that's exactly what will happen.
