What have you been banned for? choose and make a poll, to understand if something is not being detected for now...
for example i have read that there are 2 kind of exposed modules for android, 1 wich uses mock locations, and another different, wich developer say it's impossible to be detected (i think it could be possible, pokemon go doesn't have permissions to analyze all your phone), or i have read that all nox users have the same id, so using a phone, should correct this for example
