This also seems to be gameable. Suppose you have blue and green camps as described in the linked paper. And if content gets ranked high when it gets approval from both blue and green users then one of the camps may decide to promote their opinion by purposefully negatively engaging with the opposite content in order to bury it.

This seems no different from "popularity based" ranking mechanisms (e.g. Reddit) where the downvote functionality can be used to suppress other content.

Maybe the assumption is that both camps will be abusing the negative interactions? But you can always abuse more.

How is such system protected from someone manipulating the consensus by employing a troll farm (https://en.wikipedia.org/wiki/Troll_farm)?
