Who makes the final decision whether someone on our site (e.g., SOja) is following the Code of Conduct or not? The community? Moderators? Or employees of Stack Exchange?
(I intentionally distinguish moderators from the community here, although moderators are also a part of the community as well as the normal users.)
Translator's Note for Context
For us on SOja, the new CoC is something like rules given from a high position which we must follow. Of course the Meta.SE community discussed the CoC a lot and the discussion was also announced on Meta SOja, but almost all SOja users didn't join the discussion on Meta.SE because it was done in English, not in Japanese. Therefore a lot of SOja users don't know either what was changed from the old "Be Nice" policy or why it was changed. So the CoC confused SOja users. Many users aren't sure how to moderate our site according to the CoC.
Therefore I post this question here because we cannot decide the principle of moderation only on our own. I also try to get a wider attention to our issue because similar things may happen on other sites on the network.
