Pirates have cruisers, they pirate in them. Traders have jumpdrives, and "out of nowhere" capital jumpships, they jump trade in them.
But the ones that are pirating with cruisers dont submit for official faction status.
Also, QQ cant explain the questions raised in the other thread. And the cruiser you were mentioning was me. I didnt pirate you for 10 million ;-;
Did interact to decent amount of time before demanding 2 million, 500 of your cargo, and mocked the other guy who didnt speak for himself, inRP. See, everything is legal
