Here's my input, although I personally haven't fired a single shot at a trader yet.
The player in question is french.... he speaks zero english. The only way I know to speak to him is through his friend Battleship_zerstorer. He is also french, but speaks english as a second language.
As stated above the blockade was posted for tokyo-berlin. If you go to ANY other major trade route we aren't going to waste 50~ minutes to chase after you.
Like Circadian said you don't have to take diamonds to tokyo.... you can buy them a system away for 216 credits a unit (instead of 386) and you could take them 1 system away from tokyo for about 1400 instead of 1600. That leaves you with a slightly longer route minute wise (probably 45 seconds to double that depending on traffic) with zero danger and almost exactly the same proft. Don't believe me? look it up.
I really have to agree with Daedalus in the sentiment that you don't seem to get the idea of hostile multiplayer, Shadow_killer. Large transports are open to be shot at ANY moment on this server. The blockade was announced, you saw the posts and took no notice in game.
However looking at it from your point of view, he should have said give me 10% of the profit or cargo before opening fire.... which gives you a chance to run or comply.
On the other hand, if there were no blockade, and I ambushed you in my sabre (with 50 hornet cruise disruptors and 50 ripper mines) I really don't think you would get away and would be just as angry if I killed you with my missiles and nomad blasters as if I had used my battleship which I have strategically placed at Berlin.
[Let me note that I would not mind firing all 50 missiles/mines at you , and I know how to shoot the CD's so that they actually hit, and not hit the missile immunity spots. Also keep in mind I would most likely hit you at a critical pirate ambush spot while I am green or white to them so that you're just dead and there's nothing you can really do about it. This would be much less fair than the blockade, and would make people quit faster....is that what you or the Admin prefer? I think not.]
As for making my characters hostile to the liberty police? No. I use liberty space, and until certain ships or items are more ubiquitously sold I'm not going to refaction my characters. I posted the names of the pirates, that should suffice.
