Random House asks young adult writers to contractually promise not to behave immorally

Random House is asking some of its authors of young adult books to sign contracts with "morality clauses" that allow the publisher to take back your advance and cancel your book if you're caught doing anything that "damages your reputation as a person suitable to work with or be associated with children, and consequently the market for or value of the work is seriously diminished." For the record, Random House Audio published my young adult novel Little Brother and did not request this clause.
An email arrives from the Society of Author's Children's Writers And Illustrators Group. Apparently, a well-established, enormous publishing house has decided to insert the following clause into its standard contract for children's books: "If you act or behave in a way which damages your reputation as a person suitable to work with or be associated with children, and consequently the market for or value of the work is seriously diminished, and we may (at our option) take any of the following actions: Delay publication / Renegotiate advance / Terminate the agreement."
