How to prove to Google that the charge of "invalid activity" on a YouTube channel is wrong?

Question

YouTube

There is a YouTube channel.
I recently received an email with the text:

Hello!
In our advertising programs, we strive to respect the interests of all participants - publishers, advertisers, and users. Therefore, in some cases, we are forced to take action against publisher accounts whose actions may adversely affect advertisers or users. In your case, we have detected invalid activity and have decided to close your AdSense account.
Unfortunately, we are unable to provide more detailed information about the identified violations due to the protection of our proprietary control systems.
In some cases, publishers are willing to take the necessary steps to correct violations of the AdSense program policies. To do this, we have developed an appeals process. To take advantage of this, please provide us with a detailed analysis of your website traffic, including reasons why invalid activity may have occurred, and file an appeal using this form. We will review it and make a further decision. Before you file an appeal, we recommend that you familiarize yourself with the most common reasons for closing accounts.
Thank you for understanding.
Sincerely,
Google Adsense Team

Tell me, please, how to check and prove the absence of cheating on our part?
Do you need to search in the analytics available on the channel (YouTube Analytics)? Where exactly?
Unfortunately, these tools are not strong.

Answer 1

You write that you are not guilty and file an appeal. But most likely you will not be lucky.
