I'm glad the site provided a "runs at risk" list but all it actually is is a list of YouTube-based runs submitted before 1 January 2017. It doesn't show which VOD's actually are at risk of becoming unwatchable. So how as a viewer (/slash game moderator) can I tell which are?

Click on the video, and choose to watch on YouTube. Then, if the video is unlisted, you will see the "unlisted" icon below the video title.

What an amazingly, incredibly helpful response!
