Absolutely, the point of listing a university is to show status and expertise. No one is going to listen to a bunch of people whose main accomplishment is getting accepted into Cornell and San Diego State. The prestige of those institutions come from the professors, doctors, scientists, researchers, who are pushing the state of the art, not the students doing homework.

Does it invalidate the content if they're one but not the other? Why does it matter if they're professors, researchers or students? It's not like they're making profound statements or putting forward some bold crazy theory, they're asking for FB's internal stats to be validated published so it can be used for research.
