URL Shortener in Curriculum - retire

May be time to retire the URL shortener from the curriculum. Or advise on ways to secure it. After a couple years of operation and prominence in my portfolio, I recently discovered it was no longer reachable.

Following up, the app was suspended. Here is the correspondence I received:

Thank you, for bringing this to our attention. We should definitely find a way to mitigate this.

I imagine the main options are:

  1. As you said, retire the app/project
  2. Introduce a small section on readying an app for phishing attacks (i think this would be interesting)
