I think most decentralised social media networks already have these three. There is no censorship exactly because they are decentralised: you can always go to a different server. I don't see any spam there. There are some trolls, and they get blocked. When an entire server is full of trolls, some admins block the entire server. No censorship doesn't mean everybody has to be forced to read your crap. People should still be able to block assholes. If you think that that's censorship, then it's your "no spam" and "no censorship" requirements that bite each other, and decentralisation has nothing to do with it.
