Miley Cyrus caused scandal with child pornography. Namely topless photographs of 15 year old girl.
She was then forced to apologize.

Now she has retracted her regrets:

Now that the adult has approved of child pornography depicting her, is it legal and moral to possess, enjoy and distribute such pornography?

Under the same condition - approval of the now adult minor depicted - should it be appropriate to distribute even harder core child pornography?

This does require that such actions should be undertaken when the subject is a minor, depicted and the recordings preserved until the now adult model can approve publication or withhold such approval.
