I've never seen one person who was banned for using the code, considering Riot essentially allows the community to know it. I used the old Konami Code one, never been banned. Used this one the same ways, never been banned. Also, apparently the LoLStatus twitter said that it was certain users, so there isn't much of a way of knowing whether you used it or not.
