Just sheer speculation on my part, but I will say (from past experience with Nintendo) that they will only ban from cheating on competitive games. Rooting leaderboards was a big problem back in the DS days. They took some small actions against that. Never once did they take action against Wild World hacking (one could speculate that is due to a lack of resources to take action against such hacking). Whether they have these advanced scanning capabilities when they can hardly keep a steady online session going on their own servers is a question everybody should step back and ask themselves. Speculation will drive people mad. Just wait for a definitive answer.
