So if he was referred to as 'Paul' when there are millions of Pauls then you would have no problem with it even though then you'd need more context to know who he was but if he's refered to his particular handle on hn, on hn then that's excluding people from the club? It wasn't as if membership of that particular club was forced on you and it's not as if it is a secret. Lighten up. For that matter, plenty of people here are only known by their handles, so if you see a reference to some person and it does not make sense to you at first it's ok to assume that is a handle. We also don't do @xxx and such around here (at least, not unless someone indicates a twitter handle).
