I think it is a bad idea for instance admins (fediverse) to ban entire instances. Unless there is a very very very serious motive behind it. And make it public when you do. Because this will cut ties with those instances and the users from your own instance will be unable to reach anyone from those banned instances. This is a dangerous game that many on the fediverse are playing. They seem to not grasp the consequences.

If we ever ban any instance then we will first announce it to all of our users, and then make it public. But unless there is severe spam flooding our servers, I do not see a reason to do that.

Users can block other users and for some federated networks they can block entire instances. Let the users decide! Not a handful of "admins". #tromlive
