If it's on your own property, just return it.  I don't know who your founder may be, but the easiest way to remove things that don't belong on your property is to open World >>> About Land >>> Objects.  Then click the arrow near the bottom of the window to refresh the Object Owners list.  Highlight the appropriate name and select Return.  The objects will be sent back to the owner.
