Thanks, I forgot to update the filenames. Should be fixed now.
An alternative to Patreon is SubscribeStar, I have an account over there as well. They allow any content, for now.
As erotic content is against the terms of service of most payment processors (Stripe and Paypal included), enabling direct payments will probably result in a ban for the receiving merchant account. The solution offered by itch.io isn't really a solution, I'm afraid.
