Of course no one can do it, because it has nothing to do with the fact that she's from Africa. There have been fat and men-like russian athletes (in shot-put i think) with love voices, who used doping and because of this became like that, but no one cared when people made fun of them, cause it indeed is funny what people do for money and glory. Also there was no fuss about them being tested and found guilty, i won't be surprised if this case is fishy too, because it indeed looks like cheating, the only question is whether the girl knew something was not right or not.
