The French Election and How Macron's Campaign Thwarted the Hackers
Russian hacking and interference in other country's elections seems to be quite common place these days.
As reported by the New York Times (and others), French president-elect Emmanuel Macron's campaign staff became aware of attempts to sway the election by, among other things, a warning from the American NSA.
As part of their efforts to mitigate the interference, Macron's staff generated hundreds of fake email accounts, with hundreds of fake documents in the hopes that this would slow down the ability of the hackers to absorb the fake information and republish it. The fact that Macron's staff saw some of their fake information in the output of the hacker's data stream seems to show that it had some effect.

It would not surprise me to see this type of info-chaff becoming more and more commonplace as the issue of fake news becomes even more commonplace. At some point, the signal to noise ratio is going to be so high that the usefulness of the internet will be severly limited (at least in terms of news is concerned).
