Look at her handwritten statement on page 5. Forget all the crappy penmanship and story inconsistencies but look at the signature. A legal signature would be her full name or at the very least Christine M. Blasey-Ford.
She goes by “Chrissy” but it’s signed “Christy”. The last name is misspelled “Blasy”.
My legal signature is illegible and I don’t use capital letters. I don’t spell it all out either.
My handwriting, on the other hand, is very nice.
