is scammers site

hi guys
I've been agreed with one of the programmers in freelancer a special programming work in my site !!!
The programmer ask to you send the money via
At first glance I have not heard of this site before .. BUT Encouraged myself to pay via this site .
But later discovered this site managed to serve the scammers .. It does not use the site policy of paypal .
It is only protects the scammers and does not protect the victim.
Coder did not start and did not perform work assigned to him ..And also does not respond to my letters .
I tried correspondent site of But to no avail .
So I advise not to use this site to transfer money
It takes only transfer fee for the protection of personal reconciliation and the protection for scammers

Thank you
