Anti-pk doesn't mean that you don't kill, it means you don't shoot unknown people on sight and you shoot people who do it. It's actually a lot more challenging style of play, because you don't have the privilege of first shot, you can't kill random scouts and you can't use many dirty PK tactics. Being a PK doesn't make you cool and badass, just cheap. But it's good that some people play the role of wasteland losers, otherwise it would be boring.
VSB at apker because they are french and french are in-capable of killing (eg WW2)
