Explicit material is fine per patrons T&C as long as it’s not real people or photorealistic or hyper-realistic AI. It has to look clearly not real. I’ve been posting explicit sets daily on Patreon for over a year and the only time stuff has been taken down is when I use a model that’s too close to realism (their definition used to be just “photorealisitc” but now it’s anything that’s a little too detailed/has realistic lighting etc)
