In the beginning stages of botting with Pokefarmer, I would suggest not going afk. Make sure to log in via phone or whatever device will give you a UI and except rewards and pick your team and such. I would even suggest doing this after each level up but, make sure that your GPS is off and don't use wifi while logging in via secondary device. I have been doing this all the way up to level 20 and haven't had issues what so ever. You just need to be safe about using this bot and it will work flawlessly!
