Simply put, you want to play an unlawful, then expect consequences. There are enough restrictions in place on the bounty hunter ID as it is without imposing more because you had an experience which presumably you could have roleplayed in response to but decided instead to lobby for more rules. I guess the real problem here is that you got caught.
Members of known ciminal groups are bountied from place to place by lawful factions and corporate groups. A few well known individuals have big price tags on their heads. You maintain you have to do something and be caught and added to a list. This omits the fact that you most likely wiped out a few ships to acquire your tag and ID - and that interaction with the environment, despite being npc's, is part of the development of your character.
Carrying a Liberty Rogue ID eans you are a member of a known criminal group - there are no Liberty Rogue civilians. People don't get to wear Corsair ID's and pretend they are part of Crete's Emergency Athlete's Foot Treatment Clinic and therefore not actually criminals. If you want the ID, you take the good as well as the bad. Bounty Hunters are easy targets for any unlawful without any forum roleplay whatsoever - why should we impose a double standard on people playing the bounty hunter ID?
These complaints come from players who can't accept a simple fact of playing any game: you can't have everything.
A list of every single pirate character? Sure. While we're at it, let's make the Bounty Hunter and Pirate ID's Admin-issue only and make everyone who lacks imagination fly civ ID's. We can introduce the same number of restrictions on criminal ID's in response to every thread that pops up complaining about every single thing that happens in-game. How about we remove all unlawful faction bounties and make it a sanctionable offense for a pirate character to attack a lawful character without forum roleplay before hand?
The setbounty command was considered and dismissed before with good reason. Use the search function and you'll see Gronath's and my own contributions to that debate.
