The devil is in the details. You haven't responded when I asked how rep can be gamed in this use case. You have neither addressed how using stake can be gamed in this use case when I point out ways that can happen. What is the real reason you are adamantly insisting on using stake as a metric rather than rep?
You insist on using a metric that will enable more centralization of power regarding phishing attacks on Hive, while trying to claim using rep won't work, that is not supported by facts. You don't lack debating skills, you lack factual basis for this insistence on stake instead of rep. Why?
