I’m still figuring things out. My account is on lemmy.world, and I noticed that when I browse /all, I see a lot of posts in communities that are on lemmynsfw, but if I go to lemmynsfw.com directly, most of those communities don’t show. In fact, going directly, most of the posts on lemmynsfw actually look SFW - they’re on c/celebs and communities for specific people. Can anyone explain it for me?
Yes, AFAIK there’s no way to log in on one instance using credentials from another instance. And also yes, it is a server-side setting (again, as far as I know).
Honestly though, making a separate account on lemmynsfw isn’t the worst idea. That’s what I did to keep my NSFW browsing and normal Lemmying separate.
