Our systems have detected unusual traffic from your computer network. This page checks to see if it's really you sending the requests, and not a robot. Why did this happen?
If you could not receive a message directed specifically to you, you would be unable to receive anything from the internet. Lacking any further data I would say this message does not imply your browser is uniquely recognized. It addresses your network and since you are using TOR that would be the TOR Onion Routing Network.
