they cannot be resisted as they will keep coming but we can avoid them by doing research before joining and investing. I don't think there is any other way to expose their lies other than doing research
We need to know that it's not easy to do good research and bounty hunters don't need to know how to do it. A good way not to join scam campaigns is to participate in those managed by well-known and experienced bounty managers. A good bounty manager will not destroy his opinion and will only choose legit projects. By joining his campaigns only, we can greatly reduce the risk of being scammed. But of course own research should be the most important.
