Didn't Reavers have bounties themselves on pretty much everybody, so that their members could shoot things easier and did not have to worry so much about the boards and ZoI, etc? I am pretty sure they had that, and it was not deemed against the rules. However - my memory is bad - it could also be that it was kinda hidden via MercNet at that time, but if I remember correctly, it was not a rulebreak, so you should be fine.
