Why is the problem URL still available after using `git filter-repo` to handle a GitHub DMCA takedown notice?

This is completely normal because:

  1. GitHub needs some time to process cached data removal requests.
  2. The error message confirms that:
    2.1) The commit is no longer part of your current repository history.
    2.2) It just temporarily remains in GitHub's system cache.

Important:

  1. You must respond to the DMCA notice within 1 business day, even if the problematic URL is still visible in cached views.
  2. GitHub will create a support ticket for your cached views cleanup request.
  3. In your response to the DMCA notice, you should:
    3.1) Confirm you have removed the content.
    3.2) Reference your cached views cleanup request ticket number.

Here is a template for your response to the DMCA notice:

  1. I have removed the problem content from my GitHub repository.
  2. I have submitted a request to GitHub support to clear cached views (ticket #).
