I have been banned on my first account a week ago, i have created another two and tried to be very cautious. Maximum 2h per session and i was making at least 1h break, no levelling over night at all ,no sniping, no teleportation at all i have always remained in the same location (Central park New York and within 200m radius from my starting point ).
One of my new accounts walking speed was set up to walking another to jogging and sadly both have been banned today morning.
I guess making another account is pointless, Niantic won they know exactly who and when is boting. I dont think its my bad luck coz my wife's accounts has been banned as well and she boted much less than i did (to compare we created our account at the same time after first bans and my second ban came when i was level 24 and wifes when she was 21). It seems that it doesnt matter how much u bot and for how long per session if u do bot u will get banned sooner or later. I wish they could make this pokefarmer more reliable like WoW bot, i cold go years without ban if you were sensible about using it and didnt push too much.
