With the closing of ripperstore I went through my files and found an avatar with the ID of "avtr_14335c34-8ea3-4a8f-a6a7-88cba6a376a9_8390914367" How can I trace back to find the author?

Went in from curiousity, found this avatar and have been on a wild goose hunt for the avatar maker since their stuff is blacklisted on the website. Cannot find them for the life of me, and am wondering if anyone here would be able to help.
