I'd like to have all of my works removed from this site

I'm posting this because I have sent several DMCA takedown requests to remove my works, but have received no response.

Thank you

You will have to submit a DMCA via https://danbooru.donmai.us/dmca. That is the only way to have your art removed from here.

This is the kind of question only an admin can answer, because regular users are not made aware of any details of the DMCA process. If you filled out the form correctly, I assume you just have to be patient.

As somebody who uploaded many of your works, I'd like to make clear that my only motivation was helping others to find, properly credit, and discover the source of images that I thought were nice.
