Have you ever seen the movie 'Trust?' There's also a few documentaries that touch on this subject as well. "Abducted In Plain Sight" and "Are All Men Pedophiles?" Some of the "Catfished" episodes are like that as well. There was also the story of the man who lived in West Virginia who went to New York and got caught up in an 'personal sting operation,' where the woman used a picture of someone else (over 18) who lived in another state - SHE got in hot water.
Also, I was acquainted with Chris Hansen, 25 years ago, before he went to NBC. What brought that whole episode to an end was the suicide of an attorney who was never a pedophile or anything close. The person who was, used a VPN to hide his true location. After his death and the subsequent dropping of "To Catch A Predator," it was found that outside of a few family pictures of nieces and nephews, he had no porn - of any kind on his computer.
