This is probably too much work as the contest is held throughout multiple servers but since the contest was publicly advertised in the news, why can't there just be an in-game voting system via automated broadcast(s)/or an additional temporary in-game menu option that allows you to select the videos that you enjoy from the submitted list(either a post filled with the video entries from Graalians.com or a website)? Since the game already has a hold of our account information, I assume it would be easy to tell if someone is using more than one account to vote or not.. If not, then there is still the option of having only "verified" accounts(with minimum hours of ##) to vote in-game, which would be a way better option imo than having everyone sign up to vote via Graalians.com.
