I am sure this is a scam site. 100% Sure!!!

I am web developer and this user hired me for 6 projects on freelancer

Here is my profile: http://www.freelancer.com/u/tanveerjavaid.html

After get work done this employer is disappear and after a month my account balance is in negative because he did not paid me with his own card.

Also I have designed a logo for this user: http://leatherroyal.com/FishWithOutBowl.png

I will spend too much time against this site now because I had hard time due this employer.
