The regular Pirate ID can be used in the manner where you're tied to a faction, but not a part of it, to my understanding. Say, a Titan with Salamancas, Tizonas, and a Corsair tag, but a Pirate ID: he would not be a born Corsair, but at the least Corsairs supply him, si?
Wrong, you can be a pirate with no IFF...you do not have to be tied to any pirate faction.
