No, that is moderation.

These big communities were formed by people who may or may not have understood what federation means. This is the inherent implication that comes with subscribing to a community that is located on a separate instance. As long as the moderation tools are insufficient to stop rampant trolling, this is the only real reaction the instances have available If they are not willing to add a whole bunch of moderators.

Irresponsible is visiting other instances and not recognizing that what you post also reflects on your instance.
