Police investigation remains open. The photo of one of the minors included a fly; that is the logo of Clothoff, the application that is presumably being used to create the images, which promotes its services with the slogan: “Undress anybody with our free service!”
I suppose you could make a Ship of Theseus like argument there too. At what point does it matter where the parts of the picture came from. Most would probably be okay with their hairstyle being added to someone else’s picture, what about their eyes, their mouth,… Where exactly is the line?
