So I've run into a problematic situation before, in which I haven't been sure whether to report or not, and it goes something like this.
My Xenos flies to the Texas scrap fields to find some dirty junkers. After searching a bit, I find a Salvager ploughing away, fully equipped with mining lasers. I approach the junker, do my RP, and open fire, to destroy him. He flees to Beaumont, docks and comes out guns-blazing with full gunboat turrets.
So the question here is, does the transport cease to be a transport, and then is unable to undock, or does this cessation make it essential a new instance of the character, and allowed to reengage? Additionally, since we assume its made the mistake of only mounting lasers, did it ever participate in PvP?
If he docks, it counts as a PvP death in the sense that he's only allowed to come back to the system to trade.
If he docks with mining turrets after you've shot him a bit, then comes back out with gunboat turrets and attacks you then he's breaking the rules.
