you will have the risk of getting assassinated;
here's what you'll have coming to you:
Nintendo's CEO will go through a list of badass people trying to reek havoc on his company by noticing downfall of money. Then he will summon and dispatch his Ninjai team to seek and kill you.
What you can do to prevent this:
1. wear Microsoft T-shirts
2. listen to your ipod while sleeping
3. go into mt. Himalaya's secret cave, beat up a abominable snowman, steal the key from his pocket of fur and open the door to the cave, go inside and destroy an orb of life that allows Nintendo's CEO to live
Or you can think logically and know that you won't get "banned" off of DSi shop on your DSi console. O-o
