They're not much, they focus on respecting the creators and the subjects.

1• If you're not the artist, link to the pic rather than post it if'n possible
2• If you're not the commissioner nor a subject in the pic, share a link rather than the image please
3• Use content warnings, we allow uncensored non-sexual toplessness, but when it doub, CW it. All nudity, sex, genitalia and kink needs to be CW'd
4• Respect us and your fellow group members.

That's it, that's all there is, easy, right?
Want a short version? Be righteous.
