Yes they're so many factors that can drive the customer to give a bad or good review and still what restricts merchants to amplify their reviews on a site like amazon?

"Reviews" are not a "trick" but an important part of customer relation management

How much it will cost to a merchant to cycle few orders over a period of time using his own products just to post some favorable reviews on these sites (like amazon)? It may be cheaper than direct advertising and with long lasting effects. Shipping and commission expenses is the cost but could be less than other marketing methods.
