Once in a while you'll get fraud orders to an address or just bad customers and need to flag their address to not ship. You can't flag their name since they use random name changers to the same address. We see this a lot with Columbia and US freight forwarders shipping there. We would just like to flag orders (probably a tag) that have matching addresses in a blacklist database. We have a red tag we manually mark them with when we see them, but they can be easily missed.
