If the system wore to catch me it would have done it a long time ago, like within the first two weeks if not first few months. It's been years.Lol lucky. I modded my gamescore back on 360 to over 100k. After a couple of months being on the One, I got banned for a week and got all my 360 achievements taken away. All i can say is if it does happen, your gonna be exactly like me and be like " wow they finally caught me".
If you were to mod it normally then that would be the case (for high amounts).
