If we are talking bout griefing player pilots ... I don´t think this will be such a huge problem.
Space (especially now that the Beta pill is gone) is really really really insanely big.
It is rather easy to evade griefers.
If we talk about NPC pirates ... well, no matter whether against NPCs or PCs, if you learn how to succesfully evade interdictions pirates lose much of their fear potential.
It is possible to evade 90-95% of all interdictions if you have mastered your ships controls enough to follow the escape vector.
(at least if you want to evade them and don´t intend to get caught in their interdiction, to give those pesky pirates a very very bad surprise)
I don't fear NPC's, I can deal with them...... I fear the prepubescent hate filled nerd who in order to give some meaning to his bullied existence, makes the weaker gamer pay, because someone has to pay
