My experience with Freelancer was a few years ago but I can still recall my bewilderment when I found all the unexpected Freelancer fees on my credit card. When I contacted Freelancer (e-mail only) all they told me was that these fees were something I had had supposedly agreed to (to put my job needs up front or on the fast track, etc.) by clicking on one thing or another.
I told the Freelancers people that the fees which should have been clearly visible and upfront on their website were all but completely masked by a very confusing set of options and unclear pricing information, which in hindsight I felt might have even been somewhat intentional or at least not designed in the clients' best interest in terms of being clear and simple. For that reason I felt they had failed to provide full disclosure.
I came away with the strong impression that the Freelancer site at that time (don't know what it's like now) was more about their bottom line (making money) than it was about making sure clients clearly understood all the fees that would be incurred.

I had NO problem with the person who actually did the work (the freelancer himself), in fact I paid him a little extra just to show my appreciation but as for Freelancer.com, they will not be at the top of my list when looking for such a service. You can check out http://alternativeto.net/software/freelancer/ for alternative similar services).
I'm in Canada and might have actually used Freelancer.ca but I believe it would have been the same as Freelancer.com (same company).
