Google conducted an event called Mapathon project in India. If a common user subjects good maps data then they have offered prizes.Google not asked the user to collect sensitive data or classified areas even though users collected and created in Google maps. That makes Indian Govt. uncontrollable anger on Google company, India's C.B.I. (Central Bureau of Investigation) filed a complaint on Google to remove the sensitive data immediately from maps.

Some times it happens because once it goes into public hands any company or government can not control, before conducting such events only the companies should put some terms and conditions, the their program will be successful. If not it will be a thread to the company.

Conducting an event to improve Google maps is really a nice thought in social perspective but company should consult with the respected governments to tackle security issues also.
