to get real answers from humans and not marketing campaigns I constantly put reddit in my search. I feel like 5 years ago that wasn’t necessary.
A great marketing tactic is to pose as reddit users. If you have just 2-3 realistic accounts, you can ask a question as account 1, and write your answer with account 2. Now imagine a company with $$$. They can guide an entire thread.
(You have to astroturf really hard or be a part of an existing wave, astroturfing reads different, so the best you can hope for is bending the narrative a step or two)
