I use https://t.me/E621WatchBot on telegram to get notifications of new uploads matching queries. (You can specify an artist’s tag as a query.)

0. 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.)
1. Mark the media as sensitive. How you do this will depend on what interface/client you’re using.
2. 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.)

Have you considered creating something akin to doesthedogdie.com? (Not on that catch-all mess of a site, but a new single-topic thing.)

A key goal of such a site would be the hope that the existence of it might go viral (because the idea that someone would care to create such a weird thing has some novelty to it), with the hope that just maybe writers/storytellers that hear about it might in turn be prompted to think about doing something different or more interesting.

I think it’s most reasonable to compare AI use in the production of art to something like a Camera Lucida or photography itself as an art, because there are many levels of which AI could be involved in the production of art.

Is it reasonable to exclude such in a situation like an exhibition/contest of drawing skill? Yes, absolutely.

Is it reasonable to exclude them in other situations, like a general furry space where you’re allowing non-artist commissioners to upload art they had no involvement in other than money and prompting? No.

I believe that the fandom is better off for more of its members being able to express themselves and their ideas visually. Some people hold the view that a non-artist should have to pay an artist or become one in order to realize their characters and ideas. I think being discriminatory about what tools people are allowed to pick up should they wish to become an artist is not fair.

One last angle that I really wish wasn’t a thing, but I feel I have to bring up: 3D art using existing models and AI art are among the last-ditch pressure reliefs to facilitate visual expression of ideas that are unpopular. No artist should have to draw subject matter they don’t want to, but many are bullied out of drawing things like feral or feral/anthro art even though they might identify with or want to serve those interests. While in an ideal world that might be partially compensated for by some of the braver members of the fandom learning how to draw/paint/etc for themselves in order to fill those niches, it isn’t enough. Intersectional discrimination against those who choose to learn how to use AI tools to create art has a particularly disproportionate impact on unpopular demographics within the fandom.
