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.
I'm not an admin or anything, but there was a recent meta post about this topic. A lot of NSFW and political stuff is restricted but not blocked. All that means is that it won't show in any feed unless you actually subscribe to the community. If you subscribe it will show in the all-feed like normal. I think it's a good middle ground.
