Use Patreon to organize monthly payments and your more sfw stuff, and have an account on another site (like Pixiv or AO3) for more explicit stuff. Link to the Pixiv profile, not your NSFW stuff itself, especially if it's art and not a story. In general, censors come down harder on art. Do something like "for every patron at X tier, I will post one Y on [site]" as a patron reward. It's not a complete alternative–it would be better to be able to send a message to these companies that they can't turn a good profit without porn, and PayPal be damned–but as a way for individual creators to survive, that's about the best there is.
