I created a new private gallery for fakes and uploaded a single picture to it, clicked on view and this appeared. It has been just a couple of seconds after the gallery was created!
This gallery has been flagged for review
This gallery has been flagged for review and is currently unavailable
A bug perhaps, or the site detection filters going in overdrive?
Edit: Also for a test, The Gallery you requested doesn't exist!
Adding to an existing gallery, nope nada nothing.
Edit2: Status update is also non functional.
