"Freelancer," the name itself reflects some sort of richness but, that doesn't lie in its activities. This website might have been started by a thief cum bitch. Freelancer encourages some Bloody F****RS cum employers to mess up newbies and dip them into shit. Don't work on freelancer instead work great you'll automatically get the best from it.
