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.
