title: Anyway we could know the real geolocation of a person to ensure that they don't hack GPS
body: <p>Because anyone could fake their geolocation lat/long number to the app by various means. Are there any cheap and practical solution or service we could ensure that they have really stay in the same place as the geolocation they sent?</p>
  
  <p>Maybe approximation from IP Address or something like that. I just think about geolocation game like Pokemon GO that should require people to really travel to specific location</p>
