I checked lemmy.nsfw but many of them are just empty or inactive at the moment.
I know it’s gonna take time for Lemmy to grow but I don’t wanna go to Reddit for this.
Edit: my instance has defederated from the lemmynsfw instance… So I’ll just create an account there I guess.
My understanding is most NSFW posts are hidden by default unless you are logged in; if you are just visiting that instance directly and aren’t logged in with an account there and changed your settings to view NSFW content it’s gonna look pretty empty.
