There were 2 prominent court cases about Anne Franks diary being a hoax.

One with a handwriting expert who stated the diary was written by the same individual.

And a later case which used forensic evidence to show parts of the diary were written in Ball point pen, which wasn’t used until 1951.

If the diary was written in 1951, all by the same person, it was not Anne Frank.
