Posting right giving device, posting right giving method, and posting right giving program

A posting right giving method performed by a computer, the method comprising:

• acquiring region information indicating a region designated by an establisher requesting creation of a community in which posting information and receiving the posted information via a network are allowed;
• storing the acquired region information and community identification information for identifying the community in association with each other in a storage;
• acquiring positional information indicating a position of a terminal device used by a user different from the establisher while within the region designated by the establisher, wherein the position of the terminal device indicated by the acquired positional information is detected using mobile phone tracking;
• determining, in response to a request from the user to join the community identified with the community identification information, whether to allow the user to join the community identified with the community identification information based on whether the stored region information corresponds to the position currently indicated by the acquired positional information;
• executing, in response to determining the position currently detected using the mobile phone tracking and indicated by the acquired positional information is included in the region indicated by the stored region information, processing for causing the user to join the community identified with the community identification information stored in association with the stored region information;
• based on an initial position indicated by the acquired positional information not corresponding to the stored region information, periodically determining whether an updated position indicated by the acquired positional information corresponds to the stored region information at a time period designated by the establisher;
• and
• executing, based on the updated position corresponding to the stored region information during the time period, processing for causing the user to join the community identified with the community identification information stored in association with the stored region information.

A non-transitory computer readable medium storing thereon a computer program, the computer program causing a computer to:

• acquire region information indicating a region designated by an establisher requesting creation of a community in which posting information and receiving the posted information via a network are allowed;
• store the acquired region information and community identification information for identifying the community in association with each other in a storage;
• acquire positional information indicating a position of a terminal device used by a user different from the establisher while within the region designated by the establisher, wherein the position of the terminal device indicated by the acquired positional information is detected using mobile phone tracking;
• determine, in response to a request from the user to join the community identified with the community identification information, whether to allow the user to join the community identified with the community identification information based on whether the stored region information corresponds to the position currently indicated by the acquired positional information;
• execute, in response to determining the position currently detected using the mobile phone tracking and indicated by the acquired positional information is included in the region indicated by the stored region information, processing for causing the user to join the community identified with the community identification information stored in association with the stored region information;
• periodically determine, based on an initial position indicated by the acquired positional information not corresponding to the stored region information, whether an updated position indicated by the acquired positional information corresponds to the stored region information at a time period designated by the establisher;
• and
• executing, based on the updated position corresponding to the stored region information during the time period, processing for causing the user to join the community identified with the community identification information stored in association with the stored region information.
