Imagine a man is going to get married and his close friend sees that the girl his friend has chosen is not a good one [By accident, he (the friend) knows the girl's background in detail] and wants to warn his friend about that girl (but very openly and in a debate). Please have a look at my self-made sentence and let me know if the bold preposition is a correct one or I have to modify it:

• One hundred people have had their go at her before you.

Note: the number "100" here is a type of exaggeration to show an emphasis of the severity in my language and have no idea if it works in AmE.
