I was playing Mario Kart DS on my blue DSi, then I decided to go on a WFC race. Average start, Wait for players, Pick your character, pick your car, and vote a course. I won the course poll (SNES Mario Circuit 1) I got hit by a lightning bolt, until I noticed something: There was a hacker in this game! Me, and the other players got hit by the bolt. So they left. I decided to play a trick on the hacker. Once the 2nd game began, I ditched him.
If you see that hacker, his name is Hacker 101 or Hacking 101. If he changes his name, and you notice something fishy on Mario Kart DS, Post it here!
