As of now, there is no evidence to suggest that any exoplanets lack the concept of pedophilia. Pedophilia is a complex psychological disorder that occurs in humans, and it is not clear whether it would exist or be relevant in extraterrestrial civilizations. It is important to remember that our knowledge of exoplanets and potential extraterrestrial life is very limited, and we can only speculate about the societal norms and behaviors of hypothetical alien species.
