Just a working list - feel free to add to it. I realize that some of these might already exist, and I just missed them. Here’s what I’ve got so far:
- Book suggestions
- Obscure Media
- New England
- Massachusetts
- separate communities for every other state too
- Mildly interesting
- Antiwork
- Anti-Amazon
- buy it for life
There IS an instance specifically for erotica/NSFW, I believe: https://federotica.com/
There’s actually multiple: https://lemmynsfw.com
I think there is also Lemmy NSFW, but I’m not sure of the exact instance url unfortunately
