The system is allowing anyone to copyright a piece of work that isn't in the video. A Youtuber named QuackityHQ had that problem, he looked at his videos and saw one was copyrighted and looked at which person copyrighted it and saw the video clip that was apparently in the video. It wasnt a clip in his video, it was a false claim and youtube just didn't care. Okay now to what is good about YouTube, there is a variety of videos, from series to makeup tutorials, this site has it all, it restricts porn, but if you have an account with 13 plus you can still watch VEVO but some of it needs to be censored.
