Unselie, you're mixing up what is unfair in-RP and what is unfair OORP. Piracy may be unfair to trader in-RP, but within rules and gameplay, what they are doing is perfectly legitimate, available to everyone to do, and quite fair, considering traders still make a lot more than the pirates do.
Buying 8 slave liners at ~2-3 million credits so you can sell them after the prices get changed because you reported the glitch is unfair OORP. It's not legitimate, it's taking advantage of a bug for your own benefit, and has nothing to do with RP. It wasn't a fair way to make money, it was abusing game mechanics, and that is covered by rule 1.2. Do you remember that little rule about ramming capships in fighters before the caps got spin-balanced? Because it made it impossible to do anything in a BS when getting rammed to hell? Yeah, that's abuse of game mechanics too, and that is sanctionable. Why should your actions be any different when they were just as abusive?
