Yeah but you never know.
When I flashed my Xbox I rang Xbox and asked if the Xbox was safe to go online and they told me to insert a game (burnt). I did and updated the game and the guy on the phone said it was fine. After that I never got banned at all and was online for 3 years paying games unverified and weeks early. I don't know if it was luck or he did something to say my account was fine but it seemed to work.
My point is he might of done it then played innocent to get away with it, you see my point?
