There is always the baraag.net fediverse instance, but there are still no hosting alternatives for lolisho aside from pixiv, which is about to ban western users from posting/accessing the stuff.

As long as those perverts all go Bluesky or other obscure social site and stay off popular ones like X, Facebook and Reddit, I'm okay with their self-containment policy.

I'm also surprised this is even happening; I honestly expected popular social media sites to begin allowing more smut because of how clown world things were getting.
