Ohh anon, I had to think about this question and look at how I post. I seriously have no idea. I've had to watch my friends get suspended over lesser things. I've openly posted shota/loli on my bsky and survived for so long. I did get a temp suspension though. I don't trust bsky as a safe alternative for hentai artists. I'm a bit of a curmudgeon and I have a lot of complaints about bsky but aaa I'll keep it to myself for now. What I would do is:

1. Crop your image onto the shota/loli's face and remove any "sex" stuff from them, like drool, sweat, leave it juuuust to the imagination.
2. Imply it's a shota/loli, but don't outright announce it.
3. If you're able to, try to post the full image to Baraag, pixiv, or popiku and then just post that link onto your bsky post, or do what I did for awhile: add the link to the full image on the cropped pic itself. I actually recently made a popiku and plan on using it as a supplement if I decide to post spicy hentai.

Currently, baraag is down but whenever it comes back up, I seriously recommend it. It's a safe place for adults to post freely. Socmed websites are too dangerous for artists. I think this is a huge problem I have with these sites.
