-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 In addition, there's a host of possibilities (both good and bad) by being able to control a Tor relays traffic. I could be wrong, my previous findings may seem to indicate that anyone with the ability to strategically place a good number of middle and exits nodes can shape or at least control some of the Tor traffic.
ZW mentioned previously: "Tor is still using IP, so there is no way around the fact that a relay operator can observe the IP addresses of hosts in direct communication with their relay(s).", and this to me presents a problem in maintaining complete anonymity.
