I feel like at the end of the day, when a theme is announced, you follow that theme. And it's up to the person who created the theme in the first place to be as specific as possible to prevent any entry issues. It's also the participants job to not try and exploit anything written by the theme creator. We're adults here, most of us anyway.. if I were in Mau's shoes and someone entered a Ford Escort, I'd allow it because it's not technically a loophole, I think in general we should all either decide to be SUPER specific or just loosen up if someone enters something off the wall.
I upset a few people last week entering a shot from GTA, but it was within the theme regulations, so I see no need to get worked up over anyone's entry unless we're going to have extremely specific standards for entering a photo.
