Of course that all the reviews that they write are faked ones.
You are not the first one that discovered that, they are getting and asking for ETH payments before they put a review about a new ICO.
This is not new, it happens with all the other sites too.
Hey guys. Remember, in crypto sphere we cant trust anyone! ICO rating sites are lying to us, you have to do YOUR OWN RESEARCH always! Remember this, and dont let yourself be scammed!
