"Because it doesn't do what I, personally, want it to do" is not a reason to remove it. There are infils (and non-infils) who have made a habit of knocking people off the bounty board. If these people are having fun, then what do you care if the bounty board isn't quite what you need to accomplish your goals? Let the people that use it have their fun.
If the wound was intended, such as by an infil attack or by a duel, then it's all fine. Having gold wasted to flukes, however, like battle wounds... that just sucks. That is, unless having a bounty exposed a character to greater chances of wounds in battle... THAT would actually be nicer than having battle wounds not give any bounty gold at all.
