to find a fraud project is very difficult in my opinion because intelligent fraudsters will be able to fool smart people. thus making it difficult for us to distinguish between fraudulent projects and real projects. Bounty managers who have managed many bounties have also run fraud projects. that is because of the difficulty of distinguishing true and false projects.
find ? no you dont need to find them because you arent going to join a fraud campaign anyway but you just need to avoid them . you can easily avoid than searching for something to join . smart people are smart and wont get scammed easily but the not so smart people are the ones that are in dangered . bounty managers are smart guys too because they wont be a manager if they will just accept scam projects . they should only accept legit projects and not easily get tricked by the pay .
