I tried blocking kbin.social because spammers are posting a lot of junk there but I couldn’t find it while searching in “Add instance” search popup.
is it because it’s not a lemmy instance?
It would be nice if we could.
This will be fixed next release!
I would really like to manually add an address, even if it can’t be found. Not just be regulated to a picker.
One example, I want to purposefully block lemmygrad.ml. But because lemmy.world defederated from it, it’s no longer a valid option. I want to block it at the app level anyways in the event my instance chooses to refedrate.
I don’t think this is possible. To block you need to provide lemmy the instance ID.
It doesn’t need to push upstream to your lemmy home instance; it could just be a local filter.
No idea why they aren’t showing up in voyager but you can block them from the default web front-end.

Wait, then what is it?
It’s an ActivityPub protocol implementing fediverse platform. It has the equivalent of lemmy’s communities which it calls magazines, but it also has microblogging similar to mastadon mixed in.
As a result they sort of work together which is awesome, but also you get stuff like what OP is asking about.
Kbin and Mbin are their own thing in the fediverse that support communities (magazine there) as well micro blogging and other stuff.
