Brand Registry not eligible

Hello, I manage a few brands. I am attempting to accept brand registry invitation and I keep getting denied by this message:

“We are unable to proceed with the request due to account eligibility reasons You are not eligible for selling account access at this point. We reserve the right to decline requests where we have identified that your account has either been involved in abusive conduct on our website or you are related to an account that was used for such abusive conduct If you do not agree with this decision, please submit an appeal”

I have tried to appeal, and their reasoning is because I abused intellectual property? My account is healthy. I have one violation of product expired complaint low, other than that, no IP complaint violations. I have exhausted all paths to correct this. Advice would be appreciated.
