Why do some universities not publish the list of persons who obtained a degree from their institution?
Scumbags like me could include that information when I  calculate a mortgage or credit card interest rate. 

That's not a huge deal except I could implicitly include race in those calculations, because, for example, most people who go to a historically black college are black. And it'd be easy to hide behind a mathematical model by saying, "that's the model that reduces the sum of squared errors, not me breaking the law."

So universities shouldn't make that data easy for anyone to access.

(Disclosure: I wouldn't do this but I could easily see someone else doing it.)
