Can privacy tools like VPNs cause false positives in audio channel mismatch detection?

Yes, privacy tools, corporate networks, and unusual devices can make a real user look different from a typical browser. That is why a single mismatch is not enough to call someone a bot. BotRefund keeps the audio mismatch as evidence and runs it through a broader set of independent checks. This helps avoid flagging legitimate visitors who simply have a non-standard setup.
