Yeah, whenever there are human subjects there is an IRB which is necessary. But, beyond that, we didn't participate in the market in any way. We wanted to see if there was bias there, and how much of it. I think I may have used the word 'value' in a bad way in my description. Not 'value' as in 'can we exploit people?' but value as in statistical significance. E.g. if you applied for a loan and your profile picture contained yourself with a child, did that help you, hurt you, or was it neutral?
