I was curious who or what was in charge of the uploaded graphics. The front-end uploader surprised me in its functionality, if a little rudimentary in look. I was also a bit sad to see that you're not allowed to upload hoods or helmet-type heads.
That they are reviewed by real people and not some sort of algorithm or script makes me wonder if there are many in charge, and if they have any personal biases. No complaints, of course, just curious.
