The short answer is no, but the line between what is classes as sex work and what is art can get a little vague. Any nude creations, or posts with 'mature themes' will need to be marked as 'Patron Only' on Patreon. Similarly, Ko-Fi users will need to mark their pages as 'NSFW' if any mature content is displayed. Sexual services are not allowed on either site. Patreon began flagging and removing profiles as far back as 2017 that previously used the site to facilitate their income via sex work. Plenty of users felt as though they had been ostracized for being sex workers, and sex-positive creators, NSFW artists, and kink-positive creators all found themselves without a moderated place to communicate with fans and earn a safe, digital living. The decision to ban sex work was, worryingly, largely influenced by the platform's payment processors - PayPal and Stripe. Sexual services are banned in their terms of use, meaning that Patreon and Ko-Fi also have to abide by these rules, and, as a result, so does anyone else who signs up to the sites.
