If you are selling illegal services and you want to use Stripe, Paypal or anything like that, you will end up being caught, blocked and potentially sued. Yes you can use use fake information, obscure companies and whatnot, but then if you're caught you're also looking at fraud, wire-fraud, money laundering, etc. Stick to crypto and things that cannot be tracked as easy. You may be losing a chunk of your potential customers, but it is not hard to get crypto nowadays and you can make your own payment gateways.
