Well, I think that this is the main reason why so many companies like trust pilot have both the systems. You can rate the company as well and you can also offer a feedback about the services and businesses. The same goes for other sites like Sitejabber as well.
Most of the times I don't really trust all of the reviews that I see on Trust pilot website because some of them are actually paid for. This is because when you look at those reviews, you will notice that they don't look like something that is real.
