Question about detecting fake orders with Woocommerce

Seeking some advice from a Woocommerce pro. I am currently in the process of buy an ecommerce store from a person and by the looks of it, it seems to be doing pretty well. However, I noticed that some of the orders don’t have the State in the shipping address, but has the rest of the address and that looks kind of odd to me. I know that you can create a manual orders with Woo, but is it possible to fake it so that it looks like a successful store? Or is there some way I can confirm they are fake orders? Thanks
