I feel very confident this is the case. And I also suspect that most of the “bots” or “shills” or whatever other inauthentic accounts people think they are identifying are just these same types of people who have unusual posting habits or communication styles. I’ve yet to see one iota of evidence that there are any accounts masquerading as something they’re not to influence politics. The only actual bots I’ve seen are the boring spambots who just post scam links at a rapid rate.
