Simply not connecting to the internet doesn't appear to be a solution either. The rep also confirmed that Microsoft is able to ban accounts based on information collected by the console which shows when the game was played. This news is sure to come as a shock to some gamers who have already started playing the final chapter in the blockbuster Halo trilogy.
This appears to suggest that games who play Halo 3 before the official street date will only avoid a ban if they never access Xbox LIVE. Microsoft is preparing an official statement on the Halo 3 banning scandal. We'll give you more on this breaking news story as we get it." Link to Original Source
