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 @[email protected]):

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.
Did they? I just looked and my porn multi is still full of everything I expect it to be.
