Yup, that's what I mean. When you see relays as specialized Communities this totally works and mimics how people have been selecting for content that's worth reading since forever. They tend to outsource curation 90% of the time to newspapers, music labels, conferences, ....
Once you know and trust the reputation of these "publication houses" to curate for stuff that's high signal to you, you don't have to know any private info about who wrote the article, who made the album or who's on the main stage. 

If there's a new publication in the Wikileaks community for example, who cares then about how much proof of work it took to spin up the profile that signed the event? As long as the profile paid for publication, followed the guidelines, wasn't deleted by the admins and is getting interaction (from members) I'm gonna read that stuff.
