Why the next terror manifesto will be harder to track

After the horrible events in Christchurch, New Zealand last month, I spent some time tracking the terrorist’s manifesto and video as they traveled through the web. I wrote this article describing the technical aspects of how to track a file and why it is difficult, and some technologies -such as IPFS- that extremist groups will be using in the future to make removal of a file even more challenging.

Side note: I originally wrote the article for The Conversation, but since everything there is CC-licensed, the story was picked up and re-run by International Business Times, Raw Story, Alternet, International Policy Digest, and so on. I suppose that is an interesting meta-story about how my own article moved through the web.
