I would happily pay millions in bounties to clear my shipping lanes
Let me preface this by saying I'm not griefing about the loss of a cargo run; it's the lack of in-game and out-of-game mechanisms to correct/discourage antisocial behavior like piracy.
I don't pay people not to rob me; that is counter-productive and encourages bad behavior. I would happily pay someone to sweep my shipping lanes for robbers if I could verify quality of service. Similarly, I would happily pay someone to serve justice to someone who robbed me. As a trader, these services are valuable to me, to the tune of 25x100,000 credit bounties. Yes, I would pay 2.5 million credits to encourage vigilantes to kill a pirate 25 times. PC pirates are at least that annoying to me.
Here are the options I can think of to ask for, receive and pay for a policing service:
1) Take out a bounty on someone via an in-game mechanism, with payment put in escrow and transferred on confirmed kill. No such mechanism exists.
2) Hang out at a starport and message pilots to see if they're willing to take a fee. Inefficient, unreliable, unable to confirm kills, and no direct payment mechanism besides dumping cargo.
3) Sign up with some sort of player-based guild/clan/service. Still unreliable, unable to confirm kills and no direct payment mechanism. Furthermore, no in-game mechanism to actually find and connect with guild/clan/service.
4) Appeal to the community via identification of pirates and encourage vigilantes to self-correct the community. No in-game mechanism, and apparently illegal on the most popular game forum in the form of the naming & shaming ban.
5) Accept that community goals are going to be treated as honeypots by antisocial players and steer clear of them. This appears to be the only viable option, since I can't imagine it being worth a vigilante's time to hang out in a system just hoping a PC pirate comes across his display with no reliable mechanism to get paid by players who value his service.
Since my primary trade routes are basically empty of human interaction, I figure I'll return to them until I can effectively pay for policing or there's some clear signal that piracy levels are very low around community goals.
PS. Thinking about it, it might be worth a small but real-life PayPal transfer to make a PC pirate's life miserable for a bit. Market forces can still exist without in-game mechanisms... PM if you're a top-grade pilot who might be interested in assassination work.
