One of the issues here is something I posted several times many moons ago -- namely that as long as Mr. Argentino uses aliases, he's not obligated to tell the truth about anything, as is the case for anonymous posters on any forum. And as is the case for Granhoff writing under "Dancer" and "Jean Scott" and so on.
Because these are pseudonyms, what we read may be entirely 100% fiction, and they are under no obligation for it to have any factual basis. We can't sue them and so on because there is no "them." So in a legal sense, Argentino hasn't done anything wrong because whatever he posts hasn't been the "life story" of Argentino. It's been the biography of some fictional character named "Singer."
This is why, folks, people in academic journals actually sign their names to things.
Now what happens when one of these fictional characters has some internal inconsistencies in their stories that make the stories impossible to believe? They close the shop for that character and invent another one and on we go. Now those folks who have channels whereby to promote their characters (LV Advisor or Gaming Today) have motivation to keep their characters alive and consistent. So sometimes these fictional characters band together to create a universe that they sell to the public.
Kurt Flowers/Martin Strong/Anthony Curtis gets all bent out of shape, according to some, when he's publicly outed with a name other than the one he's presenting at the time. Expecting real-person biographical details from fictional characters makes as much sense as looking in the yellow pages to hire The Hulk as a bodyguard.
