You can detect proxy because the geotarget libs put vpn/tor on its own "countrycode". In fact in most advertising networks you can choice country OR "proxy". This is not perfect or updated. But you can check by hand the reverse DNS, if looks like server.com instead of isp.com you catch more. This is worth just for sales, but it is what the fraud/risk dept's of billers do, along with other tests I am not hereby disclosing.
