There may be some small amount of nuance. Like if she says a hard no vs a not now, or if time has passed and circumstances changed significantly maybe.
But I'm confident that far more often than not, being repeatedly asked out after having said no is upsetting and may be a sign of danger. Is this person who isn't accepting no on a date going to not accept no on sex, on me having friends, on other things?
Also, big norm breach, the person who said no could change their mind and reach out on their own.
