Just a historical note.
Folks, have you noticed the similarity between distribution of
keys and newsfeed? ("News" was very popular communication form
before forums, web2 and high speed internet access.[1])
News admins had to search "good" partners if they wanted to get a rich

On the top of evolution of news servers you can find INN with a lot of
sophisticated solutions.
Fraction of experiences of decades of news may be useful here too.
