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.
As far as I remember they weren't monetizing NSFW subs, so I guess their reasoning is that banning them reduces server costs while not impacting their ads revenue.
Now what will be interesting is to see how much of Reddit's userbase was there at least partly for the porn, and how many users will leave Reddit altogether because of this move
