Rules on account deletion?

A mod told me there are guidelines that mods have to follow for account deletion. What guidelines? Can you tell me? Because just saying there are guidelines comes off a bit rude. I want to know so if my acc gets hacked I know what to do. Thanks!

If your Microsoft/Xbox account becomes compromised in any way, you should reach out to Microsoft/Xbox Live support. They have information on their respective support sites regarding what to do in situations where you may have lost control of you account.
