You Tube provides this information  so you can help your friends with  issues that arise on YouTube

Q: I have a friend who may be in trouble on YouTube and may need help. How can I help them?

A: Sending them to the Safety Centre is an excellent way to get them started. They'll be able to find their issue, learn more about what they can do and report it, using the Help & Safety Tool. We'll need to hear from the person who is having the issue directly, so don't try to report the issue for them. And remember that talking to a trusted adult about the issue can be an important step in helping your friend.
