- Choose an instance where the rules don’t forbid the content you want to post. If you’re looking for exposure of your own art, you’ll particularly want to avoid choosing an instance that has onerous rules. (One example of such a rule might be that porn needs to be posted as “unlisted” or followers-only.)
- Mark the media as sensitive. How you do this will depend on what interface/client you’re using.
- Use the “content warning” feature. This is not a place for a full description. Instead, imagine it from from the perspective of someone who would not want to see it. What keywords or descriptors would be useful to allow them to know that they shouldn’t click to show it? (A useful minimum would be something to indicate that it’s illustrated or RL, that it’s furry or feral or whatever, the apparent sexes of the characters, and any extreme fetishes depicted.)
Art (!), stories, animations, fursuit photo shoots and videos, it’s all good.
Probably the only thing I’m solidly down on is animations that have voice acting and/or sound effects added, because even when it’s “good” or “well done” it still winds up being immersion/engagement-destroying for me.
