Yes, the scammer team of Yfdexf project got successful in their lousy attempt and this is just a beginning if we don't get alert there will be many more projects will exist scam, bounty and airdrop participants should have to understand this truth that they are not going to be millionaire by participating in lot of bounties in single time this is not going to happen ever so avoid those bounties and airdrops which looks suspicious in any way only focus on genuine bounties/airdrops.
The problem is it's still hard to find good projects, people do not want to promote scam projects they do not want to waste their time and their effort they only want a good project, bounty hunting is now is a hit or miss you find a project to promote and it turns out to be a scam, you find a good project but they ask a lot and sometimes did not distribute or low value.
