I don't see how content addressing helps with leaks. If I have some stolen data I can distribute it with padding on the end so it has a different address faster than you can push out blacklists.
It doesn't - my point was that leaks (as in, anything of mine that gets out) already tend to be permanent on the web. Yet, news sites, botters on social media, etc - all change their content with no paper-trail for us to follow.
Anything I leak is basically permanent on the current web. If that's the case already, why would I want a mutable system in place where people can edit what they said? Alter what was posted, alter votes, take ddos content, etc.
