commenting on others,
In my idea, the moderators list is an addressable event with a “d” tag as a topic.
I meant that we should still use kind-7 for upvotes (no one uses this as downvotes IRL), but use a new kind for downvotes (kind-77?). When reacting to topic posts, we'd add a “t” tag as the topic.
Voting for metadata might be overcomplicated, recent from moderators might be good enough as you said.
Overall, I want to ditch the pre-existing WoT or following model in favour of the new shiny topic-based model. For example, collaborative relay selection could be based on the moderators list.
