I've seen this a lot on the internet, especially on Reddit. And, I'm not saying it doesn't happen. Native advertising is everywhere now-a-days. But, people are always vague on details, which makes me somewhat skeptical. I'd be interested to hear more information on how this works. Like, what U.S. companies are doing this (either PR companies doing the posting or their clients)? How much are they paying, and what kind of outcomes do they like to see? Like, how do they measure success? Does it work? etc.
