Blocking under age users



I don’t know if this is the best place to make this request, but I was wondering if a function could be developed so that only users older than say 16+ can view both my profile and its content. The majority of my posts are aimed at a mature audience and I feel that it is my obligation (and yours) to protect our youth. To quote a very famous tv reverend’s wife ‘Think of the children! Won’t somebody please think of the children?!’

Thank you.
