Since no one else has said it… 80 days podcast:
80 Days is a podcast dedicated to exploring little-known countries, territories settlements and cities around the world. We’re part history podcast, part geography podcast and part ramble. Each episode, we’ll land in a new locale and spend some time discussing the history, geography, culture, sport, religion, industry, pastimes and music of our new location.
As with any law, there will undoubtedly be cases in which it is difficult to discern whether or not a law has been broken, but courts decide on innocence or guilt in such cases every day. A jury would be asked to decide whether a a reasonable third party is likely to conclude on the balance of probabilities that the image depicts a person who is under 18.
Whether or not the depicted person is real or imagined is not relevant in many / most jurisdictions.
