I don't know what you mean by hacked, but this would have been less of an issue if New Zealand had not tried to censor it. The Streisand effect is very real. If you're looking for a technical solution, there is none. The most valuable feature of the Internet is its resistance to censorship. Cut off one head, and two more shall take its place.

Streisand effect doesn't apply here. It's about relatively small thing being blown up by a disproportionate reply.

This isn't some small event, everyone already knows about it.

Hacked, in this case would mean that the violence was designed to drive traffic towards the manifesto, which would have otherwise vanished into obscurity. But I take your point regarding censorship.
