I'm coming from kbin. It used to be that when I blocked an instance, I wouldn't see any posts or comments from users on that instance.
Here, I blocked an instance, and I still see comments from users from that instance. Is it possible to change this and make so that their posts/comments are hidden?
Do you mean blocking a domain? So navigating to /d/domain_to:block? If you do: that block all posts that have a url linking to kbin. Since comments do not link to anything they will not be blocked by this. If you want a feature like this, please consider making an issue over on github in the mbin repo
It definitely does not block threads from those instances showing up. For example I have lemmy.ml blocked that way and I still get the occasional lemmy.ml threads pop up and have to manually block all the different communities on that instance.
