When the Microsoft servers send you a Challenge, your console is going to send a Challenge Response and this response will tell the Microsoft servers if your console is modded or not. However, a stealth server will intercept the Challenge and send a Spoofed Challenge Response saying that the console is not modded, keeping you unbanned.
