I am utterly completely appalled at YouTube customer service of how easy it is for young children to gain access to disgusting adult content videos. My child is 6 and a video he stumbled upon is such vulgar content that i went crazy.
I am happy for my children to use YouTube, but you need to create some sort of obstacle so that children can not access adult contented videos. Or even worse produce a kind of adult tube for sexual videos and YouTube for child friendly content.
