Obviously people's opinion will affect their descision. You don't intend to vote purely on he/she who applied the rule of thirds the best and making sure that any sort of dividing of the signature is done exactly in the golden section. Oh and lets not forget about lines and flow and lighting.
Sure these things are important but even if someone manages to stick to all the "rules" it's no guarantee for an eyepleasing tag. If someone gets lots of votes week afther week then perhaps people just like the style that person uses and think it's superior to other entries. People will always disagree but that's how democracy works.
Also if people really are just voting for people they like then I highly doubt hiding names will work. As mentioned above some people here have very recognisable styles.
