This is completely right. Bounty hunters dont read the rules properly at first then in the end complaint about changing of rules. This line is mentioned in many campaigns and rings bells for me. Hunters often miss these kinds of info and just jump into the campaign. I would suggest doing bounty hunting only after seeing whether the manager is trustable and reliable or not. If he is reliable and well known, then it is unlikely that he do any such thing because his reputation is on the line.
