Stripe Atlas
I just checked the prohibited businesses https://stripe.com/de/prohibited-businessesI am fine with most of them being prohibited but at some points it's getting quite restricted:1. Virtual currency that can be monetized, re-sold or converted to physical or digital products or services or otherwise exit the virtual world4. Sexually-oriented or pornographic products or services9. Engaging in deceptive marketing practices
(here: who decides what is 'deceptive')14. Age verification15. Age restricted products or services
(which are the most products/services)50. Centralized travel reservation services or travel clubs
