Not sure about any recent update, as per the latest elders book, Child pornography is considered a form of child abuse, and an abhorrent form of pornography viewing and is handled judicially (with a circuit overseer as a JC Chairman)
Chapter 13:
Chapter 3: Para 3:
Child sexual abuse is a perversion and generally includes sexual intercourse ... Depending on the circumstances of the case, it may include involvement with child pornography or sexting with a minor.
Para 6:
Child abuse is a crime. In some jurisdictions, individuals who learn of an allegation of child abuse may be obligated by law to report the allegation to the secular authorities.—Rom. 13:1-4.
