Like a lot of fundamentalist groups, Jehovah's Witnesses disregard the legal, linguistic and literary definitions of pornography and define it along purely subjective lines, which would include any portrayal of the human form that is pleasant to the eye at all.
By that definition, pretty much everyone has accessed "porn" because even the swimsuit edition of Sports Illustrated would probably qualify.
The German magazine, Stern, from which the JW's plagiairzed the picture of Pacale Petit for the Live Forever book, would definitely be considered "Porn" by JW's, which makes you wonder what they were doing with it in the first place.
