If I run two instances of wow on the same computer, and one is using the bot and the other one isn't. Is there a chance that the account that isnt using it can be banned?
Yes there is a chance, dont ask me how big it is tough. It is not guaranteed that both accounts will be banned.
In the last banwave I had one bot and my main account in the same pc at the same time. The bot got banned and my main did not.
