That site was never claimed after you deployed it anonymously, so it was not migrated to Netlify. We do still have the files, but it would be impossible for you to prove that you created it. On the third hand, the files included are pretty minimal and don’t look particularly sensitive - some fonts, 2 small gifs, and index.html
So, I can transfer it to your account if you have one with netlify and wanted to let me know the login (email address only, please!)
