Call of Duty: Modern Warfare 2 is without a doubt the best and most popular game on Xbox Live. But this can only make things worse if you get permanently banned. There have been many people and websites claiming that there are ways to remove a perm ban or to get around it and get back online. Unfortunately, these are all lies. There is no working or legal way to lift a ban on a Modern Warfare 2 account on Xbox Live. Be careful of scams related to this, as they are potentially dangerous and large in number. Instead, buy a new Xbox 360, set up a new Xbox live account, and maybe even buy a new copy of the game. Or if you feel that the ban is unjustified, speak to a customer support representative and see about getting the ban appealed.
