Gunter,

When going to that video/link, we get this message:

      This video is private.

I get this;

I am not surprised that this video quickly disappeared. It was a public youtube video... no special invitations required.

The video was about a 2-year undercover investigation into a seemingly innocent organization.

I will keep working on it.
