You'll very easily get into a situation in which you'll be attacked by locals, and it may well look like you were baiting an attack to abuse the self-defense privilege. That absolutely is against the rules.
Doing what you're describing is pretty much guaranteed to get you sanctioned sooner or later.
If you want to hunt nomad NPCs, use an Order, Core, Corsair or Zoner battleship.
ok i see where your coming from, i dont want to be sanctioned or to abuse the self defense rights,
as for getting another battleship, well i dont really wont to i like the rheinland battleship and i want to fight NPC battleships in it and the only NPC i have seen that isnt house military is nomads, so there it is, to fight a NPC battleship in my rhienland battleship i need to be where i was going, i will officially contact the core tomorrow and ask there permission to do so at a cost-or not- of there choice, if they decline my request well then i guess my hopes for that are gone, and i will likely sell my BS and join a faction against a house so i can fight NPC battleships that way without risk of getting in trouble for rule braking.
