These on-line marketplaces are crawled to obtain data of inter-user communications and this data is parsed in a network structure and its physical properties are analysed. The Configuration Model is used as a null model to investigate the patterns in these networks to reveal information about their topology. This information is applied to interpret the behaviour of users within these illegal marketplaces.Show less
