A fascinating variation on this same issue can be found in Neal Stephenson's "Fall, or Dodge in Hell". There the solution is (1) discredit weaponized social media in its entirety by amplifying it's output exponentially and make its hostility universal in all directions, to the point that it's recognizeable as bad faith caricature. That way it can't be strategically leveraged with disproportionate directional focus against strategic targets by bad actors and (2) a new standard called PURDA, which is kind of behavioral signature as the mark of unique identity.
