>>3559151990% of Pokemon Go players do at least one of the following:
-Bot
-Spoof
-Use/share multiple accounts/devices (Playing for your wife/kid/pet dog isn't any more legit than making multiple accounts for yourself)
-Acquire information not intended to be legitimately obtainable (Use of scanners, etc.)
-Use third party programs (IV Checkers)
-Use third party hardware (Gotcha)
-Abuse exploits in the programming for advantages early on (multiple devices for greater efficiency in mass evolutions and power ups)
If you fell under any of these categories even once in your account's playthrough, you are not legit. Simple as that.
