From my understanding, a pirate that has cargospace for 3.6k cargo, can pirate 3.6k cargo off you. A group of pirates that are 3x 3.6kers and 3x frigates of 2.9k can in effect pirate 19.5k cargo off of various traders/Barge pilots. That imo has never been in question.
What is in question, is why it is now a viable thing to now broadly state that an unlawful group can piracy demand a Lawful group, with huge numbers, and now be allowed to just full dump on them regardless.
Side A: Lawful. Side B: Unlawful
Side A has 10 players. Side B has 25 players.
Fleet fight was organised for Side A and Side B to fight, but Side B have too many in ordinary circumstances to fight with everyone at their disposal.
Side B now issue a piracy demand. Side B either get their demand fulfilled or get to dumpster the fleet of 10 ships.
This was originally not an issue because for the most part, people would balance and sit people out, because nobody really paid any attention to the fact that these piracy lines weren't really an aimed thing. This "Clarification" now highlights this as an easily viable "I can Gank you because you refused my piracy demand". Id like to say i agree with giving pirates some leniency, but you are going to have to be more explicit on your ruling with it. Simply allowing it to be a gank based on a single half hearted "gimme 100k per person to give you a fair fight" thats then subsequently refused because while 100k aint that much for a warship, it shouldnt be that one pirate faction should be able to extort another for simply bringing twice to three times as many people as they would ordinarily. Granted, this was always possible in the grand scheme of things, but it is now been made blatantly obvious to quite a few of the community, on a wide scale that this is the Likely Outcome. It is now a basis for Giving Ganks out. You may as well have written in the rules: "Demand first, never have to bother with fairplay with your enemies".
This isnt just concerning Unlawfuls though, is it? Anyone can demand something from a hostile that they have kill lines on. That was clarified before, so you can be looking at a whole host of other Grey Areas created by this issue because it will be taken to mean that anyone that you can blue for existing, you can pirate, or gank.
