If I understand things corrrectly, I think there is a way that some offenders could be banned with a bit of effort. First, two concepts must be considered:
1. The profile is stored in the wii, not on the server (this is why Activision says they cannot ban like on PS3/xBox)
2. The leaderboards are stored on the server (this must be true, because when you check the leaderboards, it downloads to update).
If these two things are true, then a hacked profile stored in a wii must connect to that server-maintained leaderboard system when it goes into online multiplayer (to keep adding to stats as the user plays). Still with me?...
If all of this is true, then it should be possible for dev's to go through the leaderboards and identify some of the people who are obviously hacking/ modding/ boosting based on unreal scores, time played, arrows and wii-motes in profile names, etc... and flag those leaderboard profiles.
Now, this part would actually take some effort from the dev's (good luck), but it seems feasible they should be able to design some method where a flagged leaderboard entry could not be connected with the hacked profile based inside the wii which is logging onto multiplayer and trying to get back into the server to keep adding to stats. This would basically create a roadblock for online play for those hacked profiles. The hacker would have to start a new profile to get online and connect to the server/ leaderboard system.
This all may sound complicated, but it is really quite a simple concept. If the hacked profile has to connect to the leaderboard, and they can tell who's not legit on the leaderboard, then there must be a way to stop that connection.
I admit that it wouldn't be a 100% way to stop the hackers, but it would be a start, and it would send a message. Sadly, I think that if I have thought of this, then the dev's certainly have and do not care to expend the effort.
