For a long time I posted as GUEST:Jim until I realised that there were other GUEST:Jims and I was getting the credit (or blame) for their posts too.
I wonder if all of the posts from GUEST are coming from the same person, the guy/girl with the inside dope on the affairs and parentage of the members of the Royal Family. When someone signs as GUEST, it is very easy for others to put words in their mouth.
But if this person is closely associated with the Royal Family, and how else could he/she know all the facts that he/she has been posting, (unless perhaps he/she is bullshitting us, do ya think?) perhaps he/she is not allowed to use a name in order to protect his or her privacy.
