using online epub reader resulted in epub being listed on public sites viewed page

I was using an online epub reader to read my epub the reader site was epubonlinereader.com subesquently I discovered that my epub was listed on their public sites viewed page and contacting the web site owner receives no reply.

Is there any way I would be able to remove the entry server side? it is listed on a php page script at https://epubonlinereader.com/viewed-list.php
