In what possible way is 'send us the coolest "hello world" you've got, and we'll critique your style' not an invitation to judge by appearance?

I'm going with calling them savvy :)
I wasn't specifically intending to make fun of the guy's appearance; he looks like a normal 20-something, doesn't look overweight, does look like he shaves regularly, does look like he gets sunlight, etc; it was just that after I tracked the guy down I was disappointed that he wasn't actually wearing a ninja mask in his picture (or whatever).
