Just because there sites don't line up does not mean they are hacking. It is just as you said, it has to do with the ping and framerates. We see slightly different things when spectating someone then they do. This effect gets amplified with the awp. It's annoying, I know. You more have to pay attention to the times when their sites do line up. What I mean is that aimbots will cause the player to focus in on a target too quickly and perfectly to be legit. Hacks, although a manipulation of the game, still use the game as their basis, and as such must still adhere to certain aspects of its programming. One of these being that the crosshairs must be on a target for the target to be hit. The only way around this would be if they infected their opponents computer or the server itself with a symbiotic hack that may allow this to happen. However, I am not aware of any hacks like this off hand.
