Honestly, what Ivan's saying makes a lot of sense and would make indie piracy more interesting. Of course, with the lawful playerbase as inactive as it currently is, it would also make freelancer ID'd piracy incredibly strong without frequent FR5ing.
Meh I've given this a lot of thought and a happy medium is hard to come by here. The inbetween is the spec op ID. The pirate ID is like a jolly roger, while the Junker ID is more of a general independent flag. If lawful ships see another ship flying the jolly roger, that's about fair game. Otherwise roll with Junker ID or try to SRP for a neutral pirate character with special rep and IFF.
