Can NPC's stop "pirating" you?

[Levi Payne]

Ye, I got the same problem. I'm Guild Guard and I get pirated by bounty hunter npc's for pilots that I find.
However, what you can do is just deny them the cargo and suffer the little pew pews. Rep doesn't go down unless you blow them up.
OR you can just go into cruise and run away while they still want the stuff.
