What's with this guy and why does Y!A let him get away with it?

I have ordered 10 pairs nike shoes from the website.and i received my shoes 7days later

i am so happy to the products i order,because the shoes look nice but crazy price at 39usd.
does anyone help me to check the website if they offer the real shoes real or not.
i think they are knock off,because the price is so cheap,
but any way,and the quality of the shoes is great,i like the shoes very much.
