What can the OP do, short of creating publicity of Freelancer's behaviour? There does not seem to be any protections ensuring that the author gets paid. He'll be held to the 'terms of service' - which will always be in the client or Freelancer's favour - this is not enough.
They make me think of the rent seeking nature of the 'sharing economy' which just weakens the market and distorts it because it takes advantage of people who do not have an escape. Like if you're uncertain whether you're going to have a place to sleep or eat in the next month.

...and made everything sound vastly worse. Link here: http://www.reddit.com/r/webdev/comments/243klv/freelancercom...
Basically claimed Freelancer.com had done everything correctly, and that they do accept drivers licenses. But since he didn't dispute a single thing claimed by Dustin, the only way to interpret it that he thought the confused, contradictory, run-around Dustin got from Freelancer.com's CSR reps was "correct".
