why has my xbox live account been suspended or banned

Why has my account been banned or suspended from Xbox Live?

If you did something that violates the Microsoft Services Agreement, your account may have been suspended by the Xbox Live Policy & Enforcement Team. To view your account’s enforcement history and learn more about Xbox Live suspension policies, sign in to enforcement.xbox.com. For more info, see Microsoft’s Code of Conduct Explained for Xbox Live Customers.

Consoles can be suspended from Xbox Live for a number of reasons including, but not limited to:

Console tampering: Physically opening the Xbox and modifying it to play illegitimate software.
Online fraud: Attempting to social engineer users, take over Xbox Live accounts, or other fraudulent activities.
Repeat egregious violations: Multiple actions taken on accounts on the console by the Enforcement team for disrupting the service or impacting users.
Customer Support for Xbox Live cannot undo an Xbox Live suspension for a console. Xbox Live console suspensions may also include permanent suspensions of Xbox Live accounts as well.

To avoid a console suspension, please review and follow the Xbox Live Terms of Use and Code of Conduct. We also recommend that you purchase Xbox 360 consoles new from reputable retail stores because previous owners may have violated the Terms of Use agreement which can lead to the console being suspended. Warranties on Xbox consoles are not transferable from the previous owner .

Some questions can be:

My console has been suspended. Does that mean my Xbox Live account will be suspended as well?

Suspensions for both consoles and accounts are determined by looking at a number of factors. While some Xbox Live account suspensions may be issued alongside console suspensions, they are not issued with every single suspension. To avoid having your account suspended from the service, please follow the Xbox Live Terms of Use and Code of Conduct.

If a console is suspended, what happens to the warranty?

If a console has been modified or tampered with, the warranty is void and the console is ineligible for an authorized repair, even for a fee. Please refer to the Xbox 360 console Warranty on xbox.com
