About time. I have been working on a similar problem ever since I found out about the Saudi agent that was uncovering twitter user identities to the royals (https://www.nbcnews.com/tech/security/saudis-recruited-twitt...). The main idea is to have zero knowledge for social graphs (both the connectivity and communication). The product behaves like a newsgroup clone with subscriptions and threads featuring zero knowledge (for host i.e. me and any other parties not subscribed/authorized to the topic).
