I think it would be better, as some do, if for a while only subscribers see his work, and after a few days or weeks have passed, he'll either publish it or honestly not care where things are published. A kind of temporary "exclusivity," because it's literally impossible to control where something you post will appear online. Even other NSFW creators who make videos, which involves a lot more work, do this, or they just release the video without audio or a shorter one and then, for those who pay, the full video. But hey, everyone can do what they want, but don't complain if they get a bad reputation. Followers have it as easy as hitting a button and cutting off payments if they're treated badly or rudely.
