I was mining in Alberta, I got full and I started to head to Camrose to dock. Meanwhile, a pirate logged in, but I did not meet him in game. He threw some threats into system chat to a Lane Hacker, he maybe made a demand; still, he was not on radar (he might have been cloaked as he had a cloak; I know this from a previous encounter).
I docked on Camrose without ever meeting this guy in space (he could have been cloaked). After I docked, he demanded 10 million from me, saying if I don't pay, he will kill me next time we meet.
Is it acceptable to make ademand AFTER I docked and was safe, and WITHOUT even meeting him in space?
