I've done it. My photo was at a 9 point something last time I checked if I remember correctly (it's been a while). I'm not saying I'm ugly by any means but I have a really hard time believing that I'm a 9 purely based on looks. The quality of it was crap (took it on my webcam) so maybe that's it.
I put up two picture, kind of as an experiment. One of them I liked of myself and the other my friends liked it but I didn't, then I deleted all my pics and never used it again :P on the first pic I got 8.8 and the second I got 9.3.
