This problem of Bounty hunters going without pay at the end of Tokensale will not end if the forum or reputable members do nothing about it. Many projects like Enviin, Tokenpay all had a successful ICO but never paid hunters at the end no one did anything about it.
Yes, we need to help each other in order for us to stop them, when you are having a suspicion on some bounty or project, check their credentials, check the team profile. Check if they have all the documents that will give them proof that it is true and correct. But yes, swachcoin is one of them, I have a friend who help them but they didnt pay his team.
