For example if I sub to memes or a video sub and one post in the community happens to be marked nsfw, I want to see it. What I don’t want is my “all” feed overran by nsfw. The furry content in public (imo in private too but that’s not a discussion for here) is not a good look.
I’d say file a ticket with the official Lemmy folks as a feature request.
I’d prefer this be a user-facing setting. I personally enjoy seeing… ‘all’ in … ‘all’. Though can easily see why someone may not like that.
