The issue is the spankin'-new PPA program. First worlders could engage in lead-fraud, too, so geotargetting isn't a sure fix.
You can tighten a PPA program so it only pays for paid signups, not leads/trials -- but then the fraudsters can dispute the credit charges. I don't think you can reverse the PPA commission to Google when, 60 days later, the signup money isn't there.
