Uhh, you ARE allowed to dock when being chased by pirates.. Thats how you ESCAPE the pirates.. A Train can't beat pirate fighters, how can traders be expected to win a fight? Docking is very much legal.
Also, some people's opinions of non-RP chat differs. The NovaPG taunted a docked trader, the trader taunted back. I'd say thats pretty feasible RP-chat.
