I'm mesmerized that so many of the HN crowd are willing to let some website take pictures of them in order to present some "funny/interesting results".
It just goes to show you that the vast majority of ppl don't care about privacy (FWIW, I used the site as well and didn't care at all, didn't even read the disclaimer)
I live in a big city where my face is captured in millions of frames by security cameras everyday.
I used android devices, now I use an iphone, and I keep cloud accounts and personal photos backups with both companies. I have linked-in, facebook, instagram and handful of other accounts with varying levels of personal information.
This cat is already out of the bag, and has been for quite some time.
