I hope someone can shed some light on this matter for me. We recently notice a lot of signups from international clients, but very specifically for ZA based VPS's - which are more expensive than normal shared hosting accounts. While we enjoy the business, I'm a bit concerned about fraud and need some pointers on how to check for fraudsters from other countries. In our own country this is rather easy, but I don't know how todo this with people from the USA, United Kingdom, Australia or Europe.
We already use Maxmind for fraud checking, but most of the checks are fine, and a lot of the clients do look legit, but some of them look very suspicious.
Any ideas, or pointers on this would help
