I've played all kinds of internet games, and every single one has already banned players for hacking the program. It would be idiotic to believe AH is immune to such.
Now that said, the two times I've griped about cheating, playing the film back revealed I didn't see what I thought I saw. One time there was TWO p51's and another there were TWO smoking la7's. Both times, I thought I was fighting a single plane (great SA eh?)

As for as the film I posted, I really do think it was just a warp. I posted it because it was so convenient, it was funny. If you think about it, with net delay, it would be impossible to time an intentional warp that perfectly. He wasn't seeing the exact angle I was seeing. If fact he probably never was where my front end showed him.
There's no doubt some people have hacked the front end (they get around it in other games - why not here?). But they're probably still not that good and have little effect on the game as a whole.
Worse would be unjustly accusing a player of cheating. The one time I did that (the other time I just grumbled over the squad channel ), I apologized to the player.
I think its safer to let HTC worry about any hacking.
