Operating a mobile terminal may include providing a list in memory of the mobile terminal with the list including at least one identification of a communications device remote from the mobile terminal. An update for the list may be received from outside the mobile terminal over a wireless link, and the list may be automatically updated in the memory of the mobile terminal after receiving the update from outside the mobile terminal. Communications may then be moderated based on the list in the memory. Related systems and computer program products are also discussed.
