I our case, they didn't present as pedophiles (obviously). It was a kid that was the same age (obviously not). She believed that he was another kid with older siblings, that lived wherever, and was bullied at school. How does that seem like a pedophile? At some point he started threatening that he had a bigger brother that knew where she lived, but the nice kid would protect her... or something. Turned out that they were a ring operating out of Indonesia that would, at the right time hand over to locals.

You can't educate kids to identify pedo's. Online and in Roblox they are exectly the same as them. With siblings, parents that stop them from doing stuff, and so on. There is nothing remarkable about them to educate kids or yourself about.
