I'm looking for answers from instance admins, if you're a regular user, you can still answer but it's more helpful for me to get answers directly from admins.

If a user on [instance A] asked another instance (Instance B) to remove their federated account and federated content copies from instance B (likely also banning it so content doesn't continue to flow) would the user on Instance A be in trouble with their instance admin for asking for such a thing.

Obviously it depends on the instance's rules but that's part of why I'm asking the question, to get answers from instance admins on this.

On one hand I can see how it would since, since it hurts interoperability and can create tension between instances, but on the other hand a user has the right to be in specific places or not be in those places, that probably extends to not wanting to be federated into an instance they find objectionable (assuming it is for good reasons).
