So, which tools do you use on your website to fight fraud? Basically to identify the person who signed up with you, I am talking about IP locater, SSN verification tools and Proxy detectors. If anyone knows or uses some of those tools, then share it please for me and for the DP community. I will start with one i found: http://www.ip2location.com/ they offer a package to detect an IP from their large data base, it's one of the best IP detectors if not the best one available. Robert
