In the scenario you gave, I think it is completely fine. As long as what you do doesn't effect others, which in your case it doesn't. Now if for example, in COD MW3 you had lives, and there was a cheta for more lives and we were playing online, I would see how it is unfair. But if it doesn't effect anyone, then who cares. Those who complain are losers who thin kthey are the video game Gods and need to find something better to do with their lives.
