One thing that I have noticed now on several images from the same Photographer is that he is mentioning that the images that he is posting are winners of a particular competition, including the name of the competition and the level of the award, ie "Grand Prize". I think that this also violates the anonymity rule here as it gives the view clues about where to find the photographer's identity. When I realized what was going on, I informed the photographer in my comment about the breech of the rules, but I don't know if it will be taken seriously. Actually, I think this is in bad form anyway as it adds an element of bias to the contest. It is almost as if someone is saying "My image won in another contest, so I am expecting a good vote here too". JMHO.
