Due to the large amount of messages being received over this, it’s certainly something that cannot be ignored.
Starting around 2 weeks ago, many Vocaloid and even UTAUloid YouTube videos started disappearing at an alarming rate due to claims by unknown (and false) copyright holders. The result of course is terminated videos, and even accounts. From the looks of how widespread the problem is, it is suspected that an organized group is behind the activity.
It shouldn’t be too much longer before YouTube shuts down the false claims, but there is something you can do if you or someone you know has been affected.
Users can file a counter-claim against the copyright by going to this page: http://support.google.com/youtube/bin/request.py?hlrm=ja&contact_type=copyright_counternotice
Most users should see their videos returned with view count, ratings, and comments within a couple weeks.
The video below is one of the more popular trending videos on the situation.[youtube:http://www.youtube.com/watch?v=LY6CO6FbH40]
Someone is deleting high ranked Miku Hatsune (and other VOCALOID) videos by filing false reports that the videos are infringing copyright.
If your video is deleted by a false report, please submit a counter-notification:
In most cases, the videos will be restored in a few weeks with the views and comments in tact.
