i see a lot of people recommending stripe as an alternative
and while stripe doesn't actively look for reasons to ban people for TOS infractions, they also do not actually allow their platform to be used nsfw/adult content transactions as per their terms of conduct
basically you're gonna have to get used to be as vague as possible when discussing your business in public, and keep all the details between you and your client
basically you have until sept 19 to scrub your accounts and figure out your smut alts and clean up the wording on your invoices so that there's absolutely no way an interested party could draw a direct line from your adult content and your paypal account
or you can try your luck with another service which will likely either not be available in as many countries, or be less trusted by clients, and also likely doesn't allow NSFW (stripe, square, cashapp)
