Such errors arise, for example, where an image artifact is erroneously associated to the location by software which cannot attribute a geo-position, and instead associates a latitude and longitude of "Null,Null" or "0,0".  Null Island was developed as an idea in 2011 or slightly earlier.  Since then, numerous web pages have documented this fictional landmass's flag, geography, and history.
