Why is 99% accuracy possible for a bot detection tool?

Accuracy comes from corroboration, not one browser tell. BotRefund sends each signal, such as an audio channel mismatch, into a prediction AI that weighs browser, network, device, and behavior evidence together. By seeing how all the signals fit, it can identify a visit as bot or human with 99% accuracy. That level of accuracy depends on using many independent checks rather than a simple rule.
