I've never understood FDev's design logic on this type of PVP. This player hasn't pirated you, he hasn't demanded anything and he has no tangible gains (credits, status, stat increase) from killing you. In real world terms this person would be classified as a psychopath or serial killer and would be dealt with accordingly.
This is purely his enjoyment at the detriment to yours which is poor game design.
I'm looking forward to how the new C&P system affects this but as things stand this is not gameplay I welcome so I play in private groups to avoid it.
Hopefully the C&P system will make "killers" think long and hard about where they choose to fly and will be forced into the slums, avoiding secure space which I can only image is the point of having security ratings in the first place.
Killing another player for no reason has been a valid game choice from day 1 but it hasn't had the correct means of control or restriction, which I hope will now change.
The other design feature I have never understood is how we are all part of the "Pilots Federation" and yet we can kill each other without reprisal unless the cops witness it in a non-anarchy system. Surely the PF should be having a word with the mass murderers in their guild?
This likely is not pvp and is probably griefing. Important to keep the two distinct.
