In the SNS server (103) corresponding to the fake posting filter device, the event specifying unit (604) analyzes the content of the posting informing the occurrence of a certain event, and specifies the event occurrence location (721). The inquiry destination specifying unit (605) searches the inquiry destination database (613) and specifies an inquiry destination corresponding to the location (721) specified by the event specifying unit (604). The inquiry unit (606) transmits a request for confirming whether or not an event has occurred from observation results of one or more devices to the inquiry destination specified by the inquiry destination specifying unit (605). The inquiry unit (606) receives a response to the request. The result reflection unit (607) determines the authenticity of the posted content from the confirmation result shown in the response received by the inquiry unit (606). The result reflection unit (607) executes a process corresponding to the determination result on the posting.
