Whats going to happen with that xbox ban mod menu?

So I heard theres a mod menu going around that can ban people. Is this a real issue? I've seen a lot of people talking about it but a lot of people jump on the trending train to get views. So is this a real issue and how can I pervent it if it is a issue? I've had my account for years and it holds a lot of sentimental value to it. I just don't want to lose it because a little kid got mad I killed him. Thanks...
