There are so many other ways to "influence" people's opinions by distorting what they see on their news feed, front page Google results, etc.

For instance (from Wikipedia):

> In April 2016, Correct the Record announced that it would be spending $1 million to find and confront social media users who post unflattering messages about Clinton.[1][4] The organization's president, Brad Woodhouse, said they had "about a dozen people engaged in [producing] nothing but positive content on Hillary Clinton" and had a team distributing information "particularly of interest to women".
