A system includes a server device and a plurality of user terminals. Each of the user terminals transmits a provisional user identifier, a group identifier, and activity information representing an activity of a user to the server device. For each of the received activity information, the server device selects distribution information based on the activity information, and also generates combination information including the distribution information and the provisional user identifier received with the activity information. The server device transmits a distribution information list including the combination information generated based on the activity information received with the group identifier, to each of the user terminals associated with the group identifier. Each of the user terminals acquires the distribution information included in the combination information including the provisional user identifier in the received distribution information list. |
