That's our risk as bounty hunters, will meet many scam projects. But from this problem, it must be my experience to choose a project that is not arbitrary, thus minimizing wasted work.
I read the article, I don't know all the project but those I know for sure are not scam, they made their ICO and it went well, but anyway they decided to cheat the bounty hunters. If the project is a scam we don't have a lot to complain about, the tokens would be useless anyway but GBX, just to make a name, it's a big and serious project, for sure it's not scam.
