Here's the scenario:
With 444 photos in Rust you sit down for the 5th time this week to continue to comment and score. The next photo comes up and, oddly, it seems like you've already scored it before--or something very, very similar. You open up a new browser window and search for the other image. Did you imagine it? No. Flipping between the two images you realize they are of exactly the same subject, taken at slightly different times of day (going by the shadows), and differently cropped.
You've already scored one of them and were thinking about commenting on the other.
What do you do?
Will you comment and score both trusting that no one would create separate user accounts and submit two photos?
I and two other photographers I didn't know took pictures for the bridge challenge in the same park. None of us knew what the other did. As it turned out we all photographed different bridges but easily could have all picked the same bridge.
At least I know I haven't completely lost my mind; I thought there were repeats also. I thought I hadn't actually scored it when I thought I had. At I know now.
Logically, there's no reason* for a person to create multiple accounts to submit two versions of the same photo.
*I actually thought of one for myself -- to see if they get markedly different scores from different groups of voters (due to randomizing of photos and everyone not voting on all the photos). But except for geeky research, it makes more sense that someone would create a second account to submit their "other" picture.
Just vote the photos as you see them. If they were submitted illegally they'll be DQ'd.

It isn't the same photo--it's the same subject. And we're not talking about the Statue of Liberty here! (Besides, that wouldn't fit rust, it's just oxidized. )
I do appreciate the openmindedness here. I tend to be a bit of a cynic, I guess. When I came across this, I thought about the options of friends/spouses going out together--but then I thought about my acquaintences and realized we just wouldn't interpret things so similarly--and if we did...?
