Some videos don't violate our policies, but may not be appropriate for all audiences. To comply with industry or regulatory viewing-age guidelines that fall outside of the Community Guidelines, certain advertisers can age-restrict their videos.
The uploader imposes this age restriction. It’s not due to the YouTube viewer community reporting the video. Videos that the uploader proactively age restricts are still subject to YouTube's Community Guidelines.
If you find something inappropriate, you can still report these videos and we’ll take further action if necessary. Learn more in the YouTube Reporting Center.
