These are only the most obvious ones. There are entire networks of Mainland Chinese living abroad that are sent junk products to review them as verified reviewers. Often they use overseas students. How it works is they legitimately order the the product, give it 5 stars and then get reimbursed through Wechat Pay or Zhifubao. Sometimes they get paid on top of it too. The entire system is designed so that those spending considerable amounts of time and money on cheating come out on top. Because few customers are going to scroll till page 15 and spent hours doing detective work to filter out the products with fake reviews (and even if they do it's become almost impossible). The most aggressive manipulators win and get all the business. Amazon must be aware of that but they don't do anything, in fact it's gotten worse in recent years.
