That's true, but most Lemmy clients default their sort to "Local" (only posts from the instance you registered on). I don't think there are many dedicated NSFW instances that are federated, at least not with my instance (lemmy.ml). Your experience may differ. The problem is that if few people can access and are aware of a community, then fewer people will post in it. That might explain why there is a lack of good porn communities on Lemmy compared to Reddit.

But it’s very common to have nsfw alts in other instances. My feeds in Reddit were also quite different depending on which account I was using. When people are wanting to “discover” content, they’ll find it, they don’t need to have it intermixed with their memes, news, politics, recipes, weird hobby community (ok maybe here’s overlap lol), etc.

Huh really? That's a shame, was wondering why I couldn't find many here.
