Regarding NSFW art:
If you're posting work that depicts violence, sex, horror, anything someone might find disturbing - it *has* to be behind a content warning.
Also importantly, though, you have to tag it # NSFW, and also *explain why it's NSFW*. People need to be able to make informed decisions as to whether they want to click through. Is there visible genitalia? Fellatio? Bondage? Fluids? Weaponry, blades, blood? Gore? Common phobias?
If in doubt, better to be over-cautious. 
@Curator New here, looking around. I can only imagine how intense things are for you all right now! Thank you for the warm welcome. I was resistant to content and trigger warnings at first but came to really appreciate them is a way to balance artists needs to say whatever they need to say and listener/viewers needs to protect themselves. I wrote about that here. https://medium.com/@rainperry/trigger-warnings-a-love-story-in-three-parts-b2b9ad15e172
