What is a DNS Challenge Blocked check in bot detection?

A DNS Challenge Blocked check looks for a mismatch between network facts that a real browsing session does not normally create. It is one of 106 independent checks BotRefund uses to build a picture of whether a visit is human or automated. Proxy rotation, location masking, or browser spoofing can make separate network facts disagree. This check is useful evidence, but BotRefund does not treat it as a bot verdict on its own.
