What are you 12? Your dealing with a game played by real people in the real world, yes there are many people that play poker with an ace up there sleeve, there are people that will see you drop a 10 out of your pocket and then pick it up and walk away. Some people have no scruples, and winning is everything. Bending the rules is just a means to an end for them.
Am I one that is after a score no matter what? nope, couldn't care less. If I found out that I was invincible would I relog to clear the error, nope. I'd run around and be laughing my butt off while everyone tries to kill me. Would I rack up a ton of kills while doing it, most likely not, at least I didn't the last time I fell through a hill. I could have just sat there killing tank after tank, but I only shot just to let them see where I was, best hour of GVing I ever had.
There are a lot of bad people in this world that will use any trick they can to "win". To me, its a game, if you take it to seriously you have a problem. In a case like this, film it send it in to HTC, and move on. Coming on these boards and posting all kinds of crap about so and so isn't going to do anything but cause trouble, for both "so and so" and yourself. Its just a game, nobody takes home the million dollar pot at the end of the night. Let it go.
