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.
The only thing I use Reddit for is porn, and my feed isn't empty, so either they're doing this in stages or there's some other criteria they're using beyond just being NSFW.
Seems to have been a bug and they reverted the bans.
