You did nothing wrong there. A traders first job is to trade and deliver cargo. Docking whilst being chased when you are a trader is fair game... but once you dock, you are stuck. No more trading for you for a while, matey.
Another thing, make sure it's a lawful base if you're carrying lawful goods, unless your trader is tagged differently.
I would say you should try to refrain from using ":P" and ":D" etc etc. Be a little more thoughtful in your responses. Your actual character wouldn't do that, since you're docked and they wouldn't see. But feel free to trash talk an entire wasteland to pirates, they deserve it! Theiving buggars!!
