Guys, we should have one point in mind. Trustpilot is not the ultimate decision-maker. Let's remember that at the end of the day they are just a business to make money. And it seems they blackmail a lot of businesses to switch to their paid service.
I just saw that Peachy Essay published an article on their blog explaining that TrustPilot tried to blackmail them for $4,500. Here is the blog post: peachyessay.com/blogs/peachy-essay-trustpilot/
Someone in this thread mentioned earlier that TrustPilot removed EssayShark. I had a look, and it seems they have banned EssayPro as well. Anyway, this is a dirty game these review businesses are playing.
