Brand Registry Unlinked from Seller Central

Looking for some advice, I’ve had brand registry linked to my seller central account for numerous brands.

Out of nowhere the brands were all disconnected from my seller central account.

When I go to link the brands back to my seller central account or any account, Brand registry asks me to make an appeal.

Your request to add your account Xxxxxxxx to the selected brands is declined, since the merchant account is not eligible for brand registry. 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.

The appeal asks me to answer these two questions –

What are the duties of the ‘to be added user’ in your brand?

Enter the email address of the ‘to be added user.’

I’ve been declined twice so far with an generic response back of the below –

a) your account was engaging in conduct that violates Brand Registry’s policies, such as, but not limited to, invalid notice submissions through our notice submission channels or tampering with the catalog;

b) your application or account is related to other Amazon accounts or brands that have violated Amazon or Brand Registry’s policies,

c) you are associated with one or more selling accounts as a primary owner and all of them have failed seller verification,

d) inability to provide sufficient evidence of branding on products/packaging;

e) you have a selling account that is de-activated, or f) your trademark application appears to be filed by a filing firm that may be violating US federal regulations and USPTO rules (explained below).

I have to assume the issue is linked to a) or b) due to the brand is approved and set up still in brand registry. As well as in the appeal process they state that the issue is based on abusive behavior. All of the brands are unlinkable, so it’s not a trademark issue.

At one point we did report some sellers for counterfeit product/trademark infringement that they appealed and won, but this must have been 3-4 Years ago at this point. This is the only thing I can think of. I spoke to this in the appeal, but had not have success.

Has anyone ever had this issue? Any guidance? Anything else someone can think of can be?

Thanks
