I am not sure whether this kind of IP spoofing will impact our accuracy because we will likely identify the noise and behavioral anomaly and discard the location hint derived from traceroute.

We have tons of historical traceroute data patterns, and generic traceroute behaviors are likely modeled out internally. So, if you can spoof the traceroute to your IP address, our traceroute-based location hint scoring weight for that IP address will decrease, and we will rely on the other location hints.

You have to be extremely deliberate to misguide us. But I would love to see this in action, though.

Yeah, I doubt there are more than a couple of hosts on the entire internet serving fake traceroutes anyway. Even finding hosts that don't enforce BCP38 requires quite some effort these days.
