How does a blockchain keep it safe? Safe, in conventional speech, for the time being, usually implies privacy, not immutability.
As for @booleanhunter, I don't mind the existence of ephemeral (or at least temporarily broadcast) communication. I believe it can be improved in its privacy, with or without decentralization, and can coexist with censorship-resistant media. But it's the latter that I feel it is crucial everyone has access to, while the former is just a relaxing "nice to have".
The reason to tag it with blockchain is becuase some of the data may use blockchain tenology to store sensitive data to keep it safe.

means hard to be changed over multi nodes.
