The article is devoted to the consideration of the features of using game theory to model review manipulation on marketplaces. In the course of the study, a model was proposed that is based on evolutionary theory and allows us to determine how susceptible buyers and marketplaces are to review manipulation, and what benefits all participants in these relationships receive. Special attention is paid to the audit that is conducted by the marketplace in relation to the processes of review manipulation by the seller, and the losses that the parties incur if it is detected.
