Something big is happening, as Reddit seems to have purged literally every NSFW sub they know. Reason is always "unmoderated" despite some of the banned subreddits being fully moderated.
Edit: seems to have been a bug in automation (thanks @lefty7283@lemmy.world):

It's still a good reminder on how quickly a community (or communities) thousands of people enjoy and in some cases rely upon can disappear.
Seems you're right. I tried a few subs when the original comment was posted and they didn't work but now they seem to be back.
To be fair, it's still a good thing to remember that it takes like one press of a button to kill a shitton of communities a lot of people care about.
