Off topic, but you can circumvent the NPCs blocking gates by flying into the gate manually and then going into formation (F4) with the NPC that is currently in the docking process. This triggers the jumping sequence immediately if you're in the gate.
Regarding the topic, this faction is going to have the same issue that the other vigilante faction has: Most people treat ID as inRP, which has their advantages and disadvantages. If you use LPI ID people who do not read this thread are going to treat you as LPI the same that the other faction is going to be treated as Xeno, no matter what anybody says.
Maybe using this ID makes it more convenient for you to play out your role or make everything easier to set up, but at the same time you could solve lots of issues by using Freelancer ID and let [LN], LPI etc set up a bounty board for you so you have engagement rules covered. That makes it also easier for parties (Specifically law enforcement) to interact with you.
