he creation and development of digital platforms dedicated to the sharing economy have generated discussions about some economic implications in the markets where it operates and social implications within the scope of its users’ experiences. In addition to the existence of a great diversity of digital services for the sharing of goods and services, the platformization of social experience opens the way to a new set of research practices. In fact, if the functioning of some platforms can limit researchers’ knowledge about intermediation phenomena, at the same time, the researcher’s skill can make some of their functionalities profitable by combining opportune methods and techniques.
