Just wait until the first person works out they can cause another player to wear a huge bounty cost by flying in front of people in a RES site, to trigger a bounty and then suicide on cops. Which then follows the originator of that friendly fire across the entire galaxy. They can't go anywhere, without that bounty following them.
Should make combat CGs fascinating. And people complain about cops flying in the way! lol. Ahh well. Nothing is perfect, right?
But you are right. I'm sure only the "bad people" will end up wearing the costs and this couldn't possibly have unintended consequences. Just like speeding in stations, right? Oh.
As far as I am aware (which is about as much as anyone else here) .. This 'punishment' (the re-buy thing) is only going to be applied if you "Kill" a pilot who has no reason to be attacked (i.e - no wanted status) not every PvP encounter.
But as has been pointed out We don't know yet
