It's been a while since I've done an integration with fraud prevention systems, but the credit bureaus do offer functionality like this - for instance, they can give you a red flag back if an address has been used by a number of different identities within a certain time period. This is important because often times a scam artist will have a drop that's been working well for them and they will use it for multiple scams simultaneously.
