Seems easy enough to use. For existing data perhaps its good, but that seems to mean that you would need to get scammed first before knowing what rule to set?

If your store is not based in the USA, this is a useless app to detect frauds. It's basically a filter for the data your customer types, it doesn't check credit cards, proxies, phone numbers, addresses and so on. You can't complaint about it though, as it's 100% free. If you're serious about preventing frauds, you need Subuno. Check it out on the app store.
