Substar's whole reason for existence is catering to those kicked off Patreon. As long as what you're doing is legal, they'll work with it, and my content is incredibly tame compared to some they take risks on. The people ganging up on Pateron at the time (this was political stuff, not nsfw, though it grew to that as well) tried to "cancel" Substar, and failed. So nothing's perfect, but it is somewhat battle-hardened.
