WARNING Freelancer.com is engaging in contest fraud. They are not disbursing winnings even in guaranteed contests. YOU MAY NOT BE PAID. If you win a $30 contest they will take $5 and then tell you you cannot withdraw less than $30. I won a guaranteed contest they are refusing to pay me.
I keep seeing your posting on contests. We all follow the freelance rules, guidelines, policies and we all have to have at least 30 dollars in our account before getting a dime of it. Sorry dude, this is just how they do it! We get ripped off when we do the work and the buyer doesn't pay us.
