I work for a rather large consumer goods company. We had a video taken down during a really important product launch. We had absolutely no idea why for three days.

It cost us maybe two full days of development resources + consultants + throwing money at different consultants to get an "in" to youtube to figure out why our video was taken down. About a week later we received official word from the artist and then we figured out that our consultants who made the video messed up and forgot the critical step of securing permission.

It was an expensive blunder, both from a media standpoint but also in the amount of resources we burned trying to figure out what the hell was wrong.

I'm not mad at youtube for taking the video down, but it's absurd that there's nothing in the system that would tell me why, and absolutely zero hope of figuring it out.
