I saw a presentation on e-commerce back in the 90s, and this was an astroturfing strategy that was pitched even back then. Don't post a thread about your company, post a question on one account, and then on another account post that your company is the answer. Really it's a strategy that's been around for a lot longer than the internet.
Not saying that this is astroturfing, just that this format has been around forever.
