I seem to understand that each instance can moderate its own users' content, e.g. if alice@example1 posts something problematic, the example1 mods can take action.
Instance mods can also decide to silence or block entire other instances from their instance.
Is there an in-between, where if bob@example2 posts something problematic, example1 mods could block that user or a specific post from their example1 instance, but not the whole example2 instance?
