Notice how there's never any indication by a nameless GUEST of any reason for the namelessness (aside from getting up the nose of people who don't like the practice)?

Sometimes a mention of "anonymity", which is completely irrelevant, sine using a name in no ways detracts from anonymity, sometimes "If I choose to, so what - it's legal", which is equally beside the point. Frequently "you people hate all GUESTs", which is quite untrue.
