Attempting to do so creates a system that incentivizes dishonesty and spamming. It's what happened to OKCupid.
Plus, as OKCupid demonstrated pretty well, people really choose almost entirely based on photos. Add in decision paralysis and an overwhelming number of choices, and optimizing around anything but incredible shallowness starts to seem silly.
Incidentally, I've tried a series of other dating sites that try to optimize around different things. In general, the userbases are quite small.
Sure, I wouldn't choose people with "bad" photos, but as I said, the amount of women with good photos is much much bigger than the amount of women with a good match.
I've seen all the Tinder-Swipe Apps, because of this. "Just swipe all women in your area right and choose afterwards"
At the end you sit there and have to talk with 20 women just to find out that only 1-2 of them don't think you're a weirdo. :D
