Engaging your own ID

[Reacher]

So as an Outcast player I've noticed that lately the "let's make a player faction that opposes what the NPC faction stands for, but still use their ID for the tech" has become very very popular as of late. And all these people have kept telling me or publicly that it's ok and that there is no problem shooting your own ID. Is that really so nowadays? I clearly remember people like the LR- and such being slapped for shooting their own indies that disobeyed. They've also been slapped for shooting allies that disobeyed. Now these "let's make faction that opposes the official npc lore" are obviously supposed to be an enemy and shot, but every time I interact with them I have this subtle fear that they might end up revenge sanctioning me just because they can.

So to tl;dr:
What exactly is the current rule standing about shooting your own faction ID or allied faction IDs? Is this allowed, do you need GM permission, do anyone wanting to oppose the NPC faction need to be FR5'd first?

Quite a few IDs have can attack anything in your ZOI expect transports. So that includes your same ID I suppose. Its a good check and balance that forces factions to be nice to there indies. As long as theres roleplay behind it dont see why not.
