I am working with vworker site, which was great to work. Later on I got that it is hired by freelancer.com a worst site I ever seen.
When I placed a bid, they charged me $3.5 as sponsored bid although i never clicked on it.
As per my knowledge they cheat randomely to a freelancer with this kind of cheat.
Also one Employer awarded me, and never responded, but I carged $100 (10% fee) for this.
I suggest you don't go with this site, and wish to close this site ASAP, and is there any complaint method which we can raise for this site.
