It's marketplace theft and accounts will get banned because of it.
How is it theft though? Granted I can see how some people might view this as theft but it's not like M$ is losing money as most of the things people download are gamerpics, themes and avatar stuff (when the 2 controller trick works that is) are absolutely free for certain regions so why should everyone else who can't access that content get stiffed? For instances I had to use my U.K account so I could download the Kick-Ass gamerpics because I'm a fan of the movie and don't live in the U.K, Does that mean M$ is going to ban me because I have Hit-Girl as my gamer pic? I think not as I hope they're not that stupid to ban people over something so silly, IMO I personally think the region lock thing is stupid as everyone should have the right to access what ever content M$ releases, I'm just glad everything will be region free with Xbox One as it should of been with the 360.
