if any of you know how the banning system works in WoT you would never get banned.... you need to be repeatedly reported as a bot, in fact you would have to be reported more than 100 times with-in 2 weeks to get banned, I have inside information on this point, so bot for 2 weeks and stop for 2 weeks, obviously if you are playing with a dev or Com leader then you are in trouble. my advise would be, if you are grinding credits, use lower than tier 6 normal tanks or premium tanks, seems the lower tiers expect you to be an idiot now and again, but a Ausf B starring at a wall, or a jagtiger facing the wrong direction will definitely get you reported. I have been botting for awhile now on 3 accounts and have not had any issues, I have premium accounts on all of them and I have taken then from tier 1 and have currently completed the full German tree with one of them.
Good luck!!
