I mean there are entire pages dedicated to lay out marketing strategies on reddit:

https://contentfac.com/a-complete-guide-to-reddit-marketing/
There are also useful subreddits to find examples: https://old.reddit.com/r/AstroTurfing/
And it scares me 'PR firms' exist and are named as such because the term 'propaganda' started to take on a negative connotation. Kinda like how Google became Alphabet, or Facebook became Meta. Advertising, marketing, public relations, propaganda, manipulation.... where does the distinction lie?
Do you care to give a couple cases/examples on the Reddit front? Like proven scandals where people or groups have conspired to deceive? You mention a dude from Idaho, but I'm not in-the-loop enough to get the reference.
