That's rather disheartening
The more I read lately the easier it seems to do those types of things with the Wii. I think, because the wii isn't really an online focused console there hasn't really been much thought put into that type of protection. Now that more of the games are going multiplayer it's showing up as a glaring issue. Chances are nothing will be done about it until the release of the new Wii. Bit frustrating really.
