Morons parroting propaganda looks a lot like bots parroting morons parroting propaganda. Plus a lot of people are terminally online and full of piss and vinegar. Heck the most prolific posters on the Fediverse are active nearly all of their waking hours.

Sure, it is probably amplified because that is how things go. They are probably in the middle of the pack to avoid standing out and the absolute worst or ‘obvious’ bots are probably just people who post too much and have a shitty worldview.
