Microsoft's Major Nelson quickly made note of the production on his Twitter account, and passed the video off to Stephen Toulouse, director of Xbox Live policy and enforcement, who tweeted several comments of his own. Toulouse noted that The Pro was "policing" Modern Warfare 2 modding, which can result in an Xbox Live Gold account suspension (banning a user from online play) or a complete console ban (rendering Xbox Live inaccessible).
It should be noted that iTzLuPo, the YouTube user who originally uploaded the video, admits that he is a modder in his user bio, stating, "I am now part of one of the best Glitching/modding clans there is on Xbox LIVE." He also lists "Glitching/Modding/tutorials" as so-called hobbies.
