One idea might be to make it so a person under say 12 can only access books marked in the children or teen section. But a submitter and validator would have to be sure to choose those categories for the books they submit and validate. I try to choose as many applicable categories as possible when I submit a book. I validated a book recently that came back with the Bookshare tool saying it had 14 words that were found to be adult or profanity and I know darned well this book had no such thing! I read almost every word of this book! It was not even a teen book--it was a children's book.
