You may want to remember that blocking servers in lemmy only really targets the communities and doesn't target users from the instance. So in these situations it kinda doesn't do anything. It's a common misconception that instance blocking in Lemmy is stronger than it actually is and many people think it does things that it doesn't actually do.
Users can now block instances. Similar to community blocks, it means that any posts from communities which are hosted on that instance are hidden. However the block doesn’t affect users from the blocked instance, their posts and comments can still be seen normally in other communities.
You're either confusing me with someone else or whatever app you're using is broken because I am not an instance admin here.
Also even if I was it still wouldn't be my decision alone and would be up to the rest of the team to decide, because that's how a large instance is run, you don't just go do big things like that randomly without having a discussion about it first.
