I'd like such a protocol to be designed so servers, relays, etc. are unable to censor content at the protocol level (if someone creates it, it is available) and the filtering is done on the client side.
Commonly filtered things (account block lists, post flag lists, filter rules, etc.) could be shared via the same system — indeed there could even be competing versions and everyone could follow their preferred filter source.
Users would also likely run statistical and machine learning based spam and content filters locally (perhaps on a personal relay/server of some sort, or an account on a shared one) configured to their preferences.
I would expect the infrastructure running such a network to be in the same position as Signal, who do not know the content of messages and can't censor them, leaving individual clients to figure out blocking etc. (albeit the client side options as well as ways to share configurations etc. would need to be much more advanced for a social network or similar than for a messaing app).
