Another thing about youtube that you may not have been aware of:
The short story: Comments in youtube videos featuring minors were being used by pedophiles as a way to spread obscene material. Creating a sort of soft-core child pornography ring. When this came to light many advertisers halted their ads on youtube, starting a new "adpocalypse". So just today (2-28-19) youtube announces it is turning off comments on videos featuring children.
