I just want to clarify something here, or well, a couple things.
1. Archelon, your not required to pirate.
2. Sidewinder, while the militarial factions may not be admins, they are in a way server police . Literally. It is in their job to make sure you follow server rules if there is none on to tell you to. They also enforce the particular rules of their own systems. (What classifies as their "own systems" may change, depending on the outset of a certain vote at the moment.)
However pirates are not allowed to (so this goes to Archelon as well) force you to get a new ID. They can mention to you that you need one, and they can tell an admin that you are lacking one.
Had this problem with a couple FEAR and a LaFammila yesterday. I came back from AFK and they told me to dock, unmount my unlawful ID and get a lawful one, or they would kill me. Uh, no. Not allowed. I already have a specific ID. The only actions someone can take against you if you have the 'correct' ID over level 40 is to act appropriately depending on their own faction/ID status.
