Hey Tom, first time reader here. Thanks for your thoughtful piece. I think one useful analogy for curator is "moderator". Although these roles are not exactly similar, a moderator, like a curator, understands the cultural milieu of their community and can take various actions like recommending and removing posts.
Separately, I stumbled upon this article — it talks about the same problem but without the "crypto-twist". I think it's worth a read for anyone who enjoyed your post :)
