The strategies of information are fundamentally the same as for other forms of warfare, but the operational calculus is very different.
The amount of noise from what are in many cases fairly obvious troll accounts introduced in important and high information density threads on /r/politics is staggering.
I can only surmise the intent has been to leverage Reddit's thread compression and comment ranking system to push down informative posts with lots of "active conversation" that really is just tossing low information, low quality chatter back and forth to reduce the signal to noise ratio of the comment section an bank on people getting to annoyed with the poor comment quality to bother scrolling for the good stuff that has been pushed down.
I'm also curious if tools like Masstagger are compromised yet and what the tooling of attackers may look like by comparison.
I'm sure there is much more going on that is harder to directly observe, but Reddit really is a great data source for any researchers on this topic.

I often wonder, if the government is so genuinely concerned about fake news, why do we see zero effort to educate people on general techniques to detect it, but see only substantial effort to attack specific instances of it?
