I disagree - I think it's about recognizing the realities of the situation and the best way to resolve it. The OP has learned that Freelancer.com is rather shady, and they essentially ripped him off of an amount of money that's rather modest by professional standards. The best way for OP to move forward is likely to learn how to do business as a freelancer without using these types of middlemen and write off the money lost to their mishaps. He could try suing for it, but my impression is that collecting an amount of money worth the time is unlikely. Better to spend the time establishing direct relationships with clients that need the work done and pay on time rather than trying to collect a pittance from Freelancer.com.
On the contrary, I find those who shout "Victim Blamer!" often ignore or discount the realities of the situation out of a quest for perceived justice. Getting such justice is often a long and expensive process that may actually leave the victim in an overall worse position, when it is possible at all. When there is a straightforward and practical plan that will put the victim back in a good situation without regard to causing any so-called "justice" to happen to the so-called "bad guy", well, sometimes it's best to just let it go. Karma will get them in the end.
That's not to say that there aren't situations where we do need some justice. I'm just saying pick your battles here. Not everything is worth fighting about, and things that are worth a fight are worth making sure you can win.
