Nobody here can help you.  Adobe doesn't discuss account matters in a public forum.  If you think you need one, hire an attorney for legal advice.

Best of luck.

If you did not respond to a takedown request by proving you had rights to the file, Adobe will assume the takedown request is valid, and you have been submitting files that you do not have the rights to (someone else's work, or IP or model release violation etc.). In this case you can expect to be blocked forever, and lose all your pictures and sales. Adobe have zero tolerance for this - as they should. More legal action could follow.

If you want to respond to the message you must reply to the email, hope, and wait. You will need very good explanations. DO NOT DELAY. Do not post here, the message told you what to do.

I am just a contributor and am in no way able to speak for Adobe or to understand the particular problems that have been associated with your account.  But it seems to me that the text you received from Adobe tells you what you need to do.  They have apparently identified the files that are in dispute.  If you have any evidence supporting your case, then you need to send this to Adobe (within 10 days).

This is a community of other contributors to Adobe Stock and its goal is to help people understand some of the technical difficulties they are having with images they have had rejected.  It is not for solving problems like yours.   You need to interact directly with Adobe to solve this issue.  

If you believe there has been no suspicious activity associated with your account, please provide all necessary information to support your position within 10 business days of the date of this message.
