The paid trolls want people to feel defeatist and tired, that's the point.

This is from 2015 and it's the most bang for your buck warfare:

Once we isolate key people, we look for people we know are in their upstream -- people that they read posts from, but who themselves are less influential. (This uses the same social media graph built before.) We then either start flame wars with bots to derail the conversations that are influencing influential people (think nonsense reddit posts about conspiracies that sound like Markov chains of nonsense other people have said), or else send off specific tasks for sockpuppets (changing this wording of an idea here; cause an ideological split there; etc).

The goal is to keep opinions we don't want fragmented and from coalescing in to a single voice for long enough that the memes we do want can, at which points they've gotten a head start on going viral and tend to capture a larger-than-otherwise share of media attention.

(All of the stuff above is basically the "standard" for online PR (usually farmed out to an LLC with a generic name working for the marketing firm contracted by the big firm; deniability is a word frequently said), once you're above a certain size.)
