Never had any issues but then again, I always play it super safe. I use (you need an account to see links) to quickly get the altitude/latitude/longitude of the city of my choice. (if you use it, change the dot in the coords to a comma!) If I pick a city far away from me I always ask myself "If I got on a plane to this city, how many hours of flight+transportation would it take for me to get there?" and then I don't touch my PokGO for that amount of hours. When I'm done waiting I proceed to run the bot, and when I'm done botting I wait the same X amount of hours before playing PokGO on my phone. Maybe the wait is an overkill but hey, works for me and so far zero bans.
