This contest is a sham. It was organized by the manager/agent of the girl who won, the same man who also happens to be dating or just fucking the girl who won second place. The public voting was also rigged in the most incompetent and shameless way. The lower spots were full of ugly girls who are or once worked as "escorts".
The contest is Brazilian after all, where corruption rules above eveything else even in meaningless contests as these.
