You don't have to think of ways to protect traders and miners at all times.
You don't need to have constant surveillance of every single field and lane.
It isn't your fault miners are being robbed, it's the miners fault for mining in the obvious spot without any sort of protection. Nothing stops miners from working in groups. Ever see what a couple Hegemons with Type 4's can do to a bomber? It isn't pretty. Why not have someone sitting ahead of the miners with a CD to buy the miners enough time to run away and get off plane?
We all play the game to have fun. And if that fun is being taken away because Skype/feedback/PM/whatever is bombarded with people who are complaining that they died, it stops being fun. When it stops being fun it becomes work, and I don't need a second job. People are going to get pirated, you can't stop that. If you are able to, what's the point of being a pirate? To be cannon fodder?
