How to think about censorship on a decentralized social network

The protocol should aim to be like Bitcoin and Ethereum.

Self-hosted clients are free to have zero censorship.

Hosted clients will have some level of censorship—likely too aggressive of a word in most cases, can use algorithm and/or moderation. Probably less than the average web2 purely centralized platform.

Max censorship is going to be on someone else's website, e.g. a blog comment where they are free to delete it completely.

Agreed. That’s one of the core principles of a “protocol” in my opinion.
