Now no one can cheat Pokemon Go. Now Niantic has become strict with his policies. They are permanently banning the accounts that are suspected of the following:
falsifying their locations, using emulators, modified or unofficial softwares and/or accessing Pokemon Go Clients or backend in an unauthorised manner, including through the use of third party software.
Niantic insists to provide a fair, fun and legitimate game experience for everyone. We will have to take there words for that, After all that company has given us such a wonderful game.
Recently, Niantic has done beta-testing Pokemon radar, of sorts- a revamped Nearby feature showing Nintendo monsters’ approximate location in the span of 500 meters. Hopefully this tool will make trainers to catch Pokemon rapidly and develop there army.
