Users can block communities yeah but instance admins cannot. I think instance admins should be able to control what c/All shows to an extent. Figuring out which communities to block takes time and frustrates new users. I've seen multiple posts from users complaining about certain communities or posts showing up on c/All and not knowing or caring that they can block communities. And then you gotta think about anonymous browsing, I'm sure many users browse without an account or without logging in, for both Lemmy and Reddit and other sites too, users hate creating accounts no matter how easy you make it.

I agree with this, but there's even more. Here's a hypothetical example. Let's say I want to create an instance that's a safe space for rape victims in particular. Now let's say there's a big instance that's very popular with some of the most frequented communities, but they also have one for simulated rape porn. Currently, all I can do is defederate or tell every user in my instance they should block the community (which, as far as I know, requires each of them going to the community and clicking "block" from the sidebar). It would be better if an admin could keep a community from showing up for any of their users.

At least connect let's you block instances.
