For people who think being a pirate is boring, just check here and see how many pay big credits to hunt and kill these lane sitters. While your at it, have a look at the amount that has been claimed.
Being a pirate is not easy. They sit on lanes that sometimes never see passing trade. They get engaged by huge numbers of law enforcers who hunt them relentlessly, everywhere and anywhere.
Pirates don't generally pirate for cash, they pirate for RP. Interaction. Most of these guys have a trader who buys the gunship/pirate transport/bomber for them to get them started. That means they started the same way as you did.
I admit that there are some bad examples, but believe me, thats true both sides of the legal fence and anyone who's been here a while knows thats true.
So true...
Edit: The bigger problem for pirates, well, around Liberty anyway, is the Lulerty Navy, especially when there's too many lolpirates around and they get trigger happy.
