I’m new to Lemmy and previously had an account on another instance (can’t recall which one), where I could see NSFW communities like those dedicated to adult content. However, after joining Lemmy.ml, I’ve noticed I can’t find or interact with those types of communities.

Can a Lemmy instance block its users from accessing specific communities or even entire instances that host such content ?

If so, is there a way to connect to those communities while staying on Lemmy.ml, or would I need to join a different instance ?

I’m just trying to understand how federation and instance rules work to make the most of the Fediverse.

Any insights would be super helpful—thanks in advance!
