Hi. I can't determine who are the scammers project but I prefer in finding which I think legit project by determining the moderators of the project. This way I can eliminate projects which I think only a scam. Actually, we cannot determine which one is a scam or not but the best way to do is acquire more projects so that it will not waste your time for waiting and the chance of have a scam is little. Sometimes you will know which are scam in the long run by instincts of determining them.
