I agree that "Stop", "Halt", ..... is an order given to you, just like "stop, pay a mil, drop some cargo,....", but.....
...not in system chat
Recently, i was flying with my trader, run into some npc's that disrupted trade lane... they started to fire at me... suddenly, "drop your cargo" msg showed in SYSTEM chat.... for who is that msg? npc's still shooting at me... "drop your cargo or die".. another msg in SYSTEM chat... poor that guy that is attacked by a pirate... i see only bunch of npc's around me... then, the trade line opens, i docked, but lane was disrupted again.... i got stucked in it.... cannot move, shoot, nothing... then, i noticed my shield is droping at high speed...poof...no shields....i think to myself some nasty npc's.... repair....again shields down, then hull down... repair...nothing....boooom....destroyed...by SOME PIRATE?!? he didn't ask nothing FROM ME.....
no demands should be asked via system chat... only by direct, private channels....or at least with name of the ship in demanding msg.
