The article about nicknames.
SEEIN' STARS Jan 4, 1934 had the same story.
Some fans don't want anyone to call Thelma Todd "Hot Toddy", although she was called that in her publicity and even in one of her films*. Some fans also don't want anyone to call Fatty Arbuckle "Fatty" even though he was called that in some of the movie titles. The whole thing is strange, and not likely to endear the supposedly serious fans responsible for this behavior with the general public.
