In this day and age, it's almost impossible to keep content from being proliferated freely online. Even games with the fanciest copy protection still tend to get broken and pirated quickly enough. However, it's most depressing when a high profile game sees release for pirates a month before launch. This is what has now happened to Gears of War: Judgment.
In a response to Eurogamer, a Microsoft spokesperson said the following:
"We are aware of isolated cases in which Gears of War: Judgment content has been propped on the web and are working closely with our security teams and law enforcement to address the situation immediately.
In the case of their property leaking so early it makes sense that they are getting into gear to ban users. Thankfully, these actions will only harm those who have pirated content and should not affect any innocent users by accident. How does a game get out a month early? If a developer didn't sneakily take the game home, it's entirely possible that some journalist out there with a preview copy did something tremendously naughty.
