I think hacking on main accounts is OK...The only thing is, you have to go maps where it's not obvious. If you cham, allow yourself to die sometimes. Also, play on maps like kill creek or snow valley that are in the open so your chams won't be detected. Err, no recoil, no spread, no sway, and a few others aren't noticeable unless you unload on a wall and you only hit one spot. If people do start to question you, turn your hacks off. At least for a little while.
