What kind of browser details do bot detectors compare to spot automated traffic?

Bot detectors look at hardware, graphics, fonts, audio, and operating-system details to see if they naturally fit together. A real browser usually reports details that match the device, while an automated browser may claim one device but reveal another through its processor or GPU behavior. BotRefund uses these details as part of its audio channel mismatch and hardware fingerprinting checks. It then cross-checks the findings with other evidence before deciding.
