About the notebook.community site

Hi,

This is not really related to Jupyter but this website notebook.community that scraped thousands of public notebooks in 2020 and rehosted them. One of the notebook had sensitive PII and even though the repo has been taken down in 2020 itself, the site itself is showing all the information. Anybody knows who built it and how to get in touch with them? There is no contact information anywhere. :sigh:

Would be great if anybody is aware.
Thanks.
