There is a distinction between allegations and evidence. An allegation does not become evidence unless it is corroborated with some form of proof. Prosecutors must decide whether an allegation or accusation can be proven in a court of law before they even bring a case. And even then, it is up to juries to decide if allegations stand up to scrutiny to the level of being evidence of a crime or wrongdoing. The volume or number of allegations don't matter if they don't provide any evidence of proof of wrongdoing under oath and cross examination. Otherwise, a collection of allegations carry about the same weight as a collection of nursery rhymes. And many of the best allegations have been heard in court and they did not stand up to scrutiny. (I know this is an oversimplification - there are whole books and courses on the subject)
