Sorry to hear the news, I was really sad to hear such news imagine working more than a month to a project trying to promote it and in the end they just waste effort and time. It looks like there's still a lot of scam projects running their bounty campaign in the forum.
Working hard for 2 months but in the end you wont get anything will make you very angry. Thats why every bounty hunters should make a research before joining in a bounty campaign to lessen the risk of not getting paid.
