Their logistics are 135 and the most I can get if 57!!!
In my last game they went to the enemy planets and wiped out all ships in orbit. I kept mine far away. I was the Kor Collective and everyone in my space is supposed to travel slower, but the pirates moved very fast.
My point is, I know they are supposed to destabilize the game, but since they concentrate in one gigantic fleet, they can only be taken out a few ships at a time, but this may cost you several fleets of your own. Seems to me like you ought to be able to research a much higher logistics in this event. Maybe up to 100.
It would also be cool if you could form an alliance against pirates or use "killing them" as collateral." Because when you kill pirates you are helping everyone.
