I'm convinced that something similar is happening to Boris Johnson's tweets at the moment. Every time he posts, many of the top responses are exact copies of each other saying something like "the country is behind you, my prime minister <3". It's clear to anyone that these are 'fake', and I'd imagine it has the effect of making people thing that the conservatives are trying to artificially bolster his reputation.

“My” prime minister? Ew, we don’t do that here. That makes it sound 100% fake.

Every politician does that. Check the posts of most autocratic accounts - half of them will be singing praises.
