Yes people are getting banned on Xbox live for using a lag switch to kill crota. There are multiple ways for bungie to know that you used a lag switch. Probably the easiest, is the simple fact that there is only 1 enemy killed (crota), and the fact that crota dies roughly 30 seconds from the the time the person touched the crystal. To the person that says he works in the IT field. You are an idiot sir. There is no possible way you work in any computer field or you would know that bungie can tell if a person used a lag switch. This is just a warning to people. Please go cheese him. No body really cares, and I'm sure the OP doesn't care if anyone believes him. But if you get banned for using something outside of the game/console boundaries then do not cry about it. Because you have been warned.
