As far as rogue BH's go consider the following.
Every other faction has some controlling group to manage them.
This is achieved though ownership of that factions guard system.
Guess which Guard system is unowned?
There is no controlling group for the Bounty Hunters at this time because no individual BH group has the right currently to tell other BH that they are out of line. That is why independent players that want to fly around simply killing everything that moves choose BH as a faction.
A request for ownership was made to purchase the Omega-56 system, the reply from an admin that was received, "we are dealing with other issues right now that are more important like faction requests".
I understand the admins position on this and have no issues with it but until any single group has control of that system, this problem will continue and there is not much that can be done about it.
