Why does my Xbox accounts keep getting locked?

That is the reason then. The terms of service forbid the making of multiple accounts as your activity looks like your trying to avoid bans.

The accounts and console are linked so MS can see when you create multiple accounts within a small time window for the same console. Its unusual behaviour so it gets flagged. Likely the console has been flagged and this is why your accounts keep getting
band.

Gold is also linked to an account not an xbox. There is a very high chance your xbox console has been flagged for some reason, you will likely need to speak with a support person to understand if that is the case.

Hello HappyPenguin, this is Manuela. I'm an Independent Advisor and community user like you, ready to assist with this.

I’m sorry to hear your account is experiencing some problems. If your account has been locked, please try taking the following tips into account before unlocking it one more time:

“You can use any phone number to request the security code.

The phone number doesn't need to be associated with your account.

The phone doesn't need to be a smartphone, or connected to the internet, it just needs to be able to receive text messages.

You may have to create a new password.”

Lastly, I would like to clarify that here in the forums, and we as independent advisors, are not capable of telling why your account has been locked.
However, I can recommend you to review the Microsoft Account Terms of Use: https://go.microsoft.com/fwlink/?LinkID=530144

You would have to try, add an alternative email so that later you can make it main and put your data to that new email, otherwise as you say they will continue to block your account.
