This is a complex matter and nothing is black and white. As a father of only daughter, I feel deeply about the girl. I don’t like the way how @Center is sometimes blaming the girl and her family.
But after reading everything available, I mostly agree with @GoatMama.
Also, at this point, I don’t think the school’s demand to reveal the plaintiff is unreasonable either, not at this point. This is money game now. The family is using questionable tactics to maximize the winning. The school has responsibility to own treasury and shouldn’t just hand over disproportionally large sum of cash.
