It comes of as very misplaced to categorize the app, by itself, as predatory and appalling. These are adult men and women. Why would it be such a surprise for intelligent young men in college to create an app to better determine the ratio of males to females in a class? This has long been done, by both sexes, way before convenient apps.

I'm sensing there would be no disdain or accusations of predatory behavior, if a female student created an app for picking classing where she is more likely to find dates and marriage prospects among the opposite sex. I'm almost quite sure, the same appalled people, would have no reaction or even state this as acceptable or categorize her as being smart. It seems that if male students, are doing something that would circumvent their supposed ranking based on innate attractiveness or better their odds in any artificial way, then it's something to be villainized and criminalized.
