All keys on my site install keys. They will expire after 30 days for Microsoft Office and 180 days for Microsoft Windows. So I think you needn’t report DMCA to me.
Some keys I get from the internet or Microsoft :

To use the keys listed here (which are GVLKs), you must first have a KMS host running in your deployment. If you haven’t already configured a KMS host, see Deploy KMS Activation for steps to set one up.
Then I use the KMS server to activate the Microsoft product. Microsoft allows it. So my content is legal.
If you want to report DMCA, please send an email to me: [email protected]

The following elements must be included in your copyright infringement claim:

1. Provide evidence that you are the only owner of an exclusive right that is allegedly infringed.

Please allow 1~5 business/working days for an email response. Finally, we will send the result of handling to you in the form of an email.
