there are so many such scammy project in bitcointalk. some just disappear from the radar after a while. maybe there should be some sort of warning about such projects in bitcointalk.
You are right on your own way but I think this is too difficult to recognize scam because it hurt and break the person to invest with his hard work and then someone scam then this is not fair thats why people didnt accept scam, but the way to recognize is only when you start forgetting about these things only.
