From the blog :
"Each time the bounty is paid, the victim has the option to issue it again. And again."
That sounds to me like a pro griefing mechanic. I see no good reason why you would encourage players to that kind of behaviour. There HAS to be a limit to the number of times you can issue a bounty (3 maybe ?) or people will just go get themselves killed just so they can grief the killer forever with infinite bounties.
