The issue is that anecdotes come with a whopping big side of selection bias. Sure, it's technically "information", but calling it "data" implies rigor. There are a lot of alien abduction anecdotes, but this tells you more about humans than it does about aliens.
There's no requirement that data must be exhaustive. And in most social science research, it never is (actually that is frequently the case in hard sciences, too).
