Which tactic and what is "Machiavellian" about it?
I believe the stories about Boys Town and to a lesser extent, but still the hunting parties.
While they are barely related to Pizzagate, how do these stories confirm PizzaGate?
It might be true, but I never seen or heard evidence regarding PizzaGate, only related stories which can be considered as background to it.

As for pizzagate I know what those instagram images revealed and what people have found after most of the accounts have gone private.

What?
This may be a first to me.
