Pokemon Go cheaters will be banned for life!
That's the new rule of law being handed down by developers Niantic as they seek to even the playing field and make their game a fair experience for all. If you are found to be in breach of any part of the terms of service for the game you could find yourself unable to play.
You can
but the methods that can lead to a banning are pretty obvious: changing your location to spoof the GPS, modifying the software to make things easier or accessing the game data using third party apps.
