Why do real visitors and bots differ in network timing and location signals?

Real visitors on home, mobile, or corporate networks usually have a coherent set of connection, location, language, and timing facts. Bots often use proxy rotation, location masking, or browser spoofing, which make those facts disagree. BotRefund uses the DNS Challenge Blocked check to spot these disagreements and then cross-checks them with other data. That difference is a useful signal but not a bot verdict on its own.
