Currently they seem to be running into a bit of a supply issue. I keep 'running out of people to pick'. It looks like you need something along the lines of (number_of_pics * 20) votes to get your rating back, so they have a bit of an inflationary issue. It probably doesn't help that I am male and voting on female pics. My intuition is that more males are participating in uploading/voting, so there is a gap in female picture supply.
