Why is Birdman always here!?

Every time me or my friends post a question on here Birdman responds to every single one and normally is about how the question is dumb or the wording is bad. I’m just wondering if Birdman works for TechRepublic or they is just a 30-year-old person complaining about the questions of high school students. Because we always see them on here and he’s been on here for a very long time and he’s always here.
