Are you sure it’s really geolocation blocks? Or is it anonymizer and VPN
service detection? The geoIP vendors typically sell both since one of
anonymizers’ top applications is to evade geolocation. Have customers using
peer-to-peer anonymizers wittingly or unwittingly? Customers with malware
or other PUPs hosting anonymizer services?
