There's nothing we can do, if I speak as a bounty hunter. but if I speak as an investor, of course I will be more careful in choosing a new project as an investment vehicle that I will do.. because we all know that investing in cryptocurrencies a high risk, especially for new projects.
After all, investors and bounty hunters have access to the same information, so they can do the same research. The truth is bounty hunters are lazy to check out anything about the project. It happens very often that they do not even read the rules of campaign correctly. They do the task incorrectly and then complain that they are not getting the reward. Of course scam project is a problem, but most of them are quickly spotted. Even when other users reveal the scam, bounty hunters continue to promote them. The situation will change when bounty hunters will stop being lazy and start doing better research.
