Appeal approved after a one-month rejection
Last month I received a notification that my Google Workspace violated their free account policy, and I sent an appeal immediately without making any modifications—no deleting blogs and no deleting accounts. I was certainly rejected.
After seeing recent posts about GDPR data requests from the EU in this subreddit, although I'm not an EU citizen, I sent a similar request through the privacy policy link on my Google account.

First, go to the link above on your PC, then scroll down to the bottom. There is a 'Show more info' button (sorry, I’m not 100% sure of the wording since my account is not in English).
Then a sidebar will appear; scroll down again, and you will see a 'Provide feedback' button. Now you can fill out the appeal again and ask for the evidence used to determine that your account is commercial.
Actually, I'm not sure if the above action works or if I'm just lucky, but two days later I received an email stating that my appeal was approved. I hope this can help you guys.
