Years ago on /b/ someone copypasta'd a guide like that. It was before the term even existed. Things like how to entice children, "safely" introduce them to sexual pleasure, how to treat the whole thing as a game but also a secret. It was revolting to say the least, but made me aware of how to protect my children and make them wary without scaring them, so there's that at least.
The Net is vast and infinite and the deepest divers witnessed things that they'd rather forget. Take care not to stare into the abyss too much, for the abyss stares back.
