Maybe I'll repeat someones idea, but I have to mention something about reputation and so called "oorp dock". Proposal is to adjust servers RP rules regarding those mentioned.
First there could be such a thing as undercover agents, spies, traitors that pretend to be for example Corsairs but works for Outcast. That would explain strange reputation that allowes Corsair to dock on Malta.
Second is that Thiefs and the guys mentioned above could steal ships and use them.
The same thing with the weapons. If the reputation allowes to buy them and the underground shop helps to install them - why not to use?
In my opinion developers and programmes should work on the reputation so a Bounty Hunter could not buy a Order guns.
