The bh system is kind of broken in the sense that people get targets who are skilling @ black chins quite often. This leads to 2 problems. The annoyance of being hunted as a skiller for emblem upgrades, and as a bounty hunter you get no drops or emblem upgrades because the skiller very rarely carries wealth large enough to upgrade them.
My Suggestion is to add a "on/off bounty" toggle that would allow skillers to opt out of getting bounty targets.
It may seem way out there, but realistically in osrs there is only one bounty world, and all other worlds do not provide bounties.
We do not have enough players in order to open up a second world imo, so a on/off bounty toggle would be your easiest solution I would think.
