Yes, I'm aware of the situation in Germany and itch.io was one of the few trusted marketplaces for German customers. I'm not sure what to do at this point. Any direct payments involving adult content will get sellers banned by Stripe, Paypal, etc., which is why the bulk payments by itch.io were such a great help. If another solution comes up, either here or on another platform, I'll be sure to notify you all.
