[Tesseract is a] Lemmy Frontend / UI that instances can use instead of the default. They had a secret shadow ban / block list for keyword, users, communities, instances that were not accessible via the admin UI and only pulled down at runtime so you could not see them in the source code before using it and could not modify it because no one knew about it.
Out of loop here what is this list?
stolen from another comment here
Was it only sending hashes of the list elements?
Thank you.
