Theres no need to justify or quantify how many accounts can be made. If you are making extra accounts to take advantage of this event, even if its just one account you are exploiting. You are exploiting this event by gaining items for your whole guild when you are not a new or returning player. You don't need numbers here, if you are not a new or returning player you don't get the bonuses pretty clear and simple. If you have new members with these scrolls and you did them without exploiting, then you have nothing to worry about as this is easily tracked. They did it in KR and they will do it here.
