Maybe it's in part due to photo quality. I think bodybuilders would be wise to understand that putting photos up which are poor quality or taken from a bad angle or exposing back acne, etc, is not a good idea, especially this close to a contest. It can really put a notion in judge's minds that may be hard to remove down the road. If anything, bodybuilders should post photos that are taken from very favourable angles where they look better than normal. Judges are people and this kind of thing can affect their decisions.
