Thread purged due to rampant speculation and general misinformation.
Infinity Ward reviews reports personally.
When you report to Infinity Ward via in-game menus: The report is filed and reviewed in time. It's never been guaranteed that the response is immediate, but the report does eventually get to a human for review.
There were quite a number of users that visited our forum to complain about being banned in MW3 and BO2 too. The system does work.
PS: You'll notice a few of your threads locked or deleted due to the sheer abundance of threads that you're creating which could have been answered by simply personally messaging us. JeepChick had already responded to you at one point, but you chose to simply keep posting. This should hopefully address the above concern and question.
