"The blockchain's two core properties, immutability and centrality (i.e. the ledger is distributed, but everyone's got the same one), are actually pretty bad for a social network. People can put awful stuff into the blockchain - doxx, harassment, child abuse, that you can't remove"
Blockchain is database. Website or product who use it can control and filter out what data to show. It can be on chain, but social network dont have to show it.
