Don't worry mate, I don't think merit means that much. I've been rejected two times in this (PlayBetr) campaign despite being in the top-40 for a long time, not mentioning twice in the ChipMixer's campaign (ended up as Ms. Universe's candidate). The manager has his own judgment about what kind of applicant he wants to accept based on various signals. I think this campaign need native English member who frequently posts in the gambling board.

There are opportunities here or elsewhere. Right attitude brings good luck
