And the person can return to the bounty board and get the money which I put up?
It would be worth it because if they die, to a person who is "hunting" them, they could lose their pvp outlaw rank or get a debuff or something. You could group up with other players and kill the person and share the reward.
And say if you have a bounty on your head, you get certain perks like being able to buy from a certain vendor or something or a cheaper repair cost for your equipment etc.
If I had a bounty on my head, it would be awesome because I would appreciate the wilderness a bit more, it would help me to survive more etc. Of course it would be better end-game because otherwise you wouldnt be able to do quests etc
