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!

I recently started using Bluesky and noticed something interesting. Under the "Getting Started" section, it says things like "Teach our algorithm what you like." Bluesky is supposed to be decentralized, so why does it even have an algorithm? Isn’t the whole point of decentralization to avoid centralized control, including things like content algorithms? Is this algorithm centralized, or is it designed to run locally within the decentralized structure (like on individual servers)?
