Google had organized its mapping contest, ‘Mapathon,’ from February 2013 to March 2013 in India. It invited users to help Google map local hospitals, eateries and places of worship in India. Users with the most number of published edits would win prizes such as Samsung tablets.

Turns out the contest was too successful.

Some users apparently marked defence installations and other classified establishments that are not marked in regular official maps published by the Survey of India (SoI), the country’s official mapping and survey organization. The agency cried foul and the Central Bureau of Investigation (CBI) has opened an investigation against Google.
