"Sorry, no more codes avaliable today" wth?

They say: "vote for crossfire everyday and win 750gp" however i just can't get my 750GP and i'm sure there are some people getting codes 3 times per day, this is not fair.... they COUNT every vote and we can't vote more than 1 time with the same IP address per day, they wait for our votes to check if there's a code for reward... -_-

We are good for vote BUT not to get codes?!
