Moderation is an impossible job. With every decision, there will be unhappy parties, and occasionally a decision will be wrong. We need moderators, and I for one am grateful to those who are willing to do the work.
What matters is that mistakes, if they do happen, are noted and lessons are learned.
It seems that the current case has led calckey to a review of its moderation processes. A constructive outcome, and good news for a federated network.
