That's how some companies manipulate trust scores and ratings on a few platforms like Trust Pilot. Suppose, A casino like 1xBit scamming people every day. Everyone doesn't rate them on Trust Pilot or so. If 1xBit starts buying fake reviews. They will becomes the most trusted casino (LOL). This is the sad reality. If a newbie searches on the internet about the rating of a specific platform and sees a good rating. But, after that, they get scammed by the platform. That's what happening today. So, people don't earn by selling fake reviews. They do scam others by selling fake reviews.
We should be aware of them. This thread should be deleted by the moderator.
