How is rent a coder?

Tweet

I have just visited the site named as rent a coder. This site seems to be fascinating. They show software project on which you need to bid. After seeing your resume the prospective client will chose you. If complete project will be accepted then they will make the payment through rent a coder. Rent a coder will charge 15% and forward the remaining amount to your account. Seems interesting and worthy of attempting. Has any one tried it and if yes, whether got the payment?
