Actually that's not true. Anne frank's dad was a publisher and when he found out that Anne was writing a diary he mentioned publication to her. She even adapted parts of her diary with publication in mind. I'm not sure if that means she embelished or if she ommited personal parts, they weren't very clear on that.

But if you don't count WW2, Anne really didn't use promo.
