Coming from a kid who can't even buy beer yet and manipulates his gamerscore. Your cool
If you really look at it (Not taking shots or defending anyone), I'll rather have a hacked gamer score than 60k k!lls. If I was bored enough I would do it anyway, instead of sitting there putting hours in everyday on video games. Maybe he didn't feel like earning it, so he hacked it to save time in his life. Which means he actually has one. Yeah, it's pointless, but sitting in a cave playing video games is even more pointless. Pointless things are produced by boredom.
That's just my view on it.
I'll rather spend 5 mins to hack 20,000 points than you to play almost 100 games which can be almost a month of my life earning....which gives me more time to do other things.
