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.
I do this in sync as it is. Just saying if a shitload of reddit refugees come here and my feed becomes 90% full of porn, I'll likely have a few more to ban.
As far as I can tell, you can only block communities in sync which is why you're having to do it one by one. Jerboa you can just block the whole NSFW instance, one and done.
