I cant be the only one botting on 5 accounts at once... I have never heard of anyone who has been banned on all of their accounts, made 5 new accounts and gotten banned on all of those within 24h after creation.
Maybe you where unlucky and got a GM on you, then he looked you up and saw that you've made 5accs who aslo where online and looked at then then saw/assumed that you where botting.
My friend and his buddys where banned on all of their accounds a while ago.
