Conclusion
Over the period covered, the International IQ Test generated more than 16.5 million results associated with unique IP addresses.
Even stricter internal filters are applied when compiling the annual rankings to help prevent cheating.
To reduce abuse and prevent bots and cheaters from adapting, these stronger filters are not published. The same anti-bot and anti-cheating controls are applied consistently—without exception—to all results included in the rankings at the time the annual rankings are compiled.
