Review spam is a generic term used to describe reviews that are not genuine.
Review spam can be negative: posted, paid for or encouraged by competitors of a business (or people and businesses related to that competitor).
Review spam can be positive: posted, paid for, or unfairly encouraged by the business or product owner (or people and businesses with a vested interest in the well-being of the reviewed business or product).
