I uploaded a video to youtube, it got stolen by other people, I reported it, and the copy got taken down in about a day. They stole it again several more times, and then it was taken down in about 30 minutes after reporting. I can't really complain. First to upload to youtube does not mean owner. What if something was uploaded to vimeo, or to a person's own website, then someone steals it and uploads it to youtube. Does that give the thief the right to take down all other copies? Or what if something is CC licensed like Big Buck Bunny, does that give the first person to upload to youtube the right to stop all other people uploading to youtube?
