It's not a problem, but it does send a signal--probably one that is a slight benefit as an adult in a technical line of work, but it might send a different signal for let's say, a teenager who is already struggling to fit in with peers. It may be a stereotype, but stereotypes exist regardless of how easy you or me think it is to register a domain. Sure someone could follow just a few simple steps found on the internet, but why does that person even care to?
