User Place Reports
Place Report requests are used to add new Places, or delete existing ones.
  New Places will be available immediately in Place Searches initiated by your
  application, and will enter the moderation queue
  to be considered for Google Maps. A newly-added Place will not be available
  to other applications until it has been approved by the moderation process.
Places that have been added by your application can also be deleted, until
  they have been moderated. Once moderated and added into the full Place
  Search results, a Place can no longer be deleted. Places that are not
  accepted by the moderation process will continue to be visible to the
  application that submitted them.
