Thank you for reaching out, @Dmitriy Kozlov !
I'm going to follow up privately to get some additional information from you as well as post some general information for anyone else who may run into this scenario.
What happens if my account is disabled?
What should you do if you find that your account has been disabled for a violation of the Terms of Service?
- Review the Terms of Service - Make sure that you review the Terms of Service so that you are aware of anything that may constitute a violation and take corrective action: Microsoft Azure Legal Information / Microsoft Azure Offer Details / Azure Terms of Service (you'll need to scroll down a bit)
- Check your email - For many violations of Terms of Service, you should receive an email that is sent to the address associated with your Azure subscription that provides additional information so that you can correct the violation. Check your email to see what action needs to be taken.
- Create a support request - Violations are reviewed by our security team and inevitably some issues will require a second look. You can also ask for issue to be revisited by creating a support ticket, either online or through the portal by searching for Help + support and clicking on Create a support request (Issue type: Subscription management / Problem type: Re-enable my subscription).
