If you're under 16, your content, and the uploading of it, should be supervised. Why are we letting our children run free on the Internet? You wouldn't let them run free on a highway and the Internet is just as dangerous but in different ways.
I believe YouTube need to implement a system of age verification for content creators. 16+ minimum if you ask me. If the parents do the uploading, whelp, you found your issue (if any arise)
