Delete old skin

I created and uploaded a skin a few years ago to Nova Skin, and the skin has my real name on it. I have tried logging into my account to delete the skin but it says that the skin was created by anonymous. Is there any way I could go about deleting my skin? I have already reported it but so far that has done nothing. In addition, is there any contact information for someone in Nova Skin that I could contact who could help me with deleting my old skin?
