I don’t have one at the moment, at least for my circles (artisans, craftspeople, adult creators in general). Much of it has fallen back on PayPal for folks without an LLC to hide behind, or Square if they’re incorporated as a business. The trick has been discretion and operating in a gray area: “novelty goods”, “graphic design work”, and “outerwear” as item descriptors or db entries, obscuring the actual content without actually lying or deceiving the payment processor.

Most paypros, most of the time, won’t look too hard unless there’s a problem or you’re tripping some internal security measure (like raking in a lot of cash in weird amounts). Of late they’ve been more intrusive due to some weird eTeen puritans, but that’s quieting down again as they remember they like making money, and throwing legal content off their platforms can very quickly cause an exodus of customers looking to avoid having their funds seized.

That's pretty clearly deceiving. Would expect to run into problems with that kind of approach regardless of the specific payment processor -- everyone has T&C that you must follow.
