Well, again, I will give the Outcast Battleship example.
Let's say Captain Rodriguez of the Outcast Battleship 'Barcelona' is sighted in New Berlin, and gives his in-character reason as being 'I fancied some sauerkraut, so decided to take the Barcelona for a spin round to the delhi by the Ring to shoot down some transports and steal their munchies.' Of course, he'd be referring to NPC transprts, so as not to break any rules, but still, this would infuriate me.
