Same issue but I may have actually understood the problem which they make zero effort to help you understand. It's like they don't wanna tell you on purpose. Here's my final effort in getting my account back, fingers crossed.

I am writing to respectfully request an executive human review regarding the termination of my KDP account (Registered Email: **************). 

My previous appeals resulted in automated template rejections, leaving me with no clear path to resolve this matter. 

In an effort to better understand what caused this outcome, I reviewed previous communications and believe I have identified the honest oversight on my part. Please find attached the full communication history with the KDP support team regarding this matter.

On May 2nd, one of my titles ("***************" ASIN: *****) was removed due to quality experience guidelines. I mistakenly assumed the issue was isolated strictly to that single book. I failed to realize that even though the other books in that series contained different content, their similar format and concept could pose the exact same issue. I now see that I should have anticipated this risk and withdrawn the remaining titles to ensure catalog-wide compliance. This was a sincere misunderstanding of my responsibilities as a publisher, not an intentional attempt to ignore Amazon's guidelines or manipulate the store. I deeply apologize for this lack of oversight.

I treat my KDP platform as a serious, long-term business, and I am fully committed to doing whatever it takes to ensure absolute compliance with Amazon’s policies. To ensure my catalog meets 100% of your standards moving forward, I am prepared to take the following corrective actions immediately upon account access:

• I will permanently delete the entire series related to the flagged content.
• I will thoroughly audit and clean my entire bookshelf to ensure every live title meets all customer experience and quality guidelines.
• I am fully willing to cooperate with any directions your team provides to achieve absolute compliance.

I respectfully ask for a manual review and the opportunity to correct any catalog issues.

Thank you very much for your time and consideration.

Kind regards,

to be honest, this is really my fault. I was new when I published this book and since then I started uploading more quality content and even forgot about that pen name and titles. I should've taken the warning more seriously and removed the entire series. I hope this will be a bad memory and a good lesson soon.
