While the other person was way to negative in their response, I can definitely see their point. How does being a CTO automatically confer knowledge of how DNS works, especially in very technical detail? Seems to me a clear case of an appeal to authority argument, which is usually (and probably also in this case) a logical fallacy.

I'm sorry to hear that, I hope they have better luck hiring in the future.

Why should someone have to serve http explaining to you what they're using their domain for? Why can't someone just have a domain for email and SSH and be left the fuck alone?
