According to another article, Keyser only knew about it, because Ford told her about it back then.
Are you sure you’ve got the right person. I think you’re confusing Keyser with some woman on FB who made a post about how she heard about it all over school, and then took her post down claiming she had no first hand knowledge.
Ford’s own lawyer released a statement that they didn’t discuss it:
Debra Katz, a lawyer for Ford, dismissed Keyser not remembering noting that Ford did not discuss the alleged incident publicly for years.
“It’s not surprising that Ms Keyser has no recollection of the evening as they did not discuss it. It’s also unremarkable that Ms. Keyser does not remember attending a specific gathering 30 years ago at which nothing of consequence happened to her,” Katz added in a statement to NBC News.

You’re mixing up Keyser with someone else.
