Weckert's tome was arguably ghost written by Kuhnen.
I can't think of anything original about the Holocaust by Rimmy (or anything original on any other subject other than Zundel, for that matter)
Nor did Pinque ever publish that I am aware, so we only have Bradley Smith's word that she was a revisionist rather than a garden-variety antisemite.
Which leaves us one -- and there's one in every crowd.

All of the named persons wrote articles for denier journals or websites which are no different to the articles written by men for the same outlets. Weckert contributed several pieces written after Kuehnen had died; I don't find it very persuasive to argue that Kuehnen ghost-wrote Feuerzeichen since his own writings are totally different. Weckert was the sole female contributor to Grundlagen zur Zeitgeschichte aka Dissecting the Holocaust. That was out of 12-15 writers.
Another 'big fish' is Carolyn Yeager, who may be an absolute jackass, but has published a brochure guide to Auschwitz (short and terrible), and runs a sub-site of CODOH.
The online contingent seems to be about 98% male. CODOH forum has just over 500 members when you eliminate the known double counted sockpuppets, and I don't think there are much more than 10 members who have even claimed to be female.
