This is a +Tor Exit Router

+ +

+Most likely you are accessing this website because you had some issue with +the traffic coming from this IP. This router is part of the Tor Anonymity Network, which is +dedicated to providing +privacy to people who need it most: average computer users. This +router IP should be generating no other traffic, unless it has been +compromised.

+ + + + +

+ + +

+ +

+Tor sees use by many +important segments of the population, including whistle blowers, +journalists, Chinese dissidents skirting the Great Firewall and oppressive +censorship, abuse victims, stalker targets, the US military, and law +enforcement, just to name a few. While Tor is not designed for malicious +computer users, it is true that they can use the network for malicious ends. +In reality however, the actual amount of abuse is quite low. This +is largely because criminals and hackers have significantly better access to +privacy and anonymity than do the regular users whom they prey upon. Criminals +can and do build, +sell, and trade far larger and more +powerful networks than Tor on a daily basis. Thus, in the mind of this +operator, the social need for easily accessible censorship-resistant private, +anonymous communication trumps the risk of unskilled bad actors, who are +almost always more easily uncovered by traditional police work than by +extensive monitoring and surveillance anyway.

+ +

+In terms of applicable law, the best way to understand Tor is to consider it a +network of routers operating as common carriers, much like the Internet +backbone. However, unlike the Internet backbone routers, Tor routers +explicitly do not contain identifiable routing information about the source of +a packet, and no single Tor node can determine both the origin and destination +of a given transmission.

+ +

+As such, there is little the operator of this router can do to help you track +the connection further. This router maintains no logs of any of the Tor +traffic, so there is little that can be done to trace either legitimate or +illegitimate traffic (or to filter one from the other). Attempts to +seize this router will accomplish nothing.

+ + + +

+Furthermore, this machine also serves as a carrier of email, which means that +its contents are further protected under the ECPA. 18 +USC 2707 explicitly allows for civil remedies ($1000/account +plus legal fees) +in the event of a seizure executed without good faith or probable cause (it +should be clear at this point that traffic with an originating IP address of +FIXME_DNS_NAME should not constitute probable cause to seize the +machine). Similar considerations exist for 1st amendment content on this +machine.

+ + + +

+If you are a representative of a company who feels that this router is being +used to violate the DMCA, please be aware that this machine does not host or +contain any illegal content. Also be aware that network infrastructure +maintainers are not liable for the type of content that passes over their +equipment, in accordance with DMCA +"safe harbor" provisions. In other words, you will have just as much luck +sending a takedown notice to the Internet backbone providers. Please consult +EFF's prepared +response for more information on this matter.

+ +

For more information, please consult the following documentation:

+ +

+That being said, if you still have a complaint about the router, you may +email the maintainer. If +complaints are related to a particular service that is being abused, I will +consider removing that service from my exit policy, which would prevent my +router from allowing that traffic to exit through it. I can only do this on an +IP+destination port basis, however. Common P2P ports are +already blocked.

+ +

+You also have the option of blocking this IP address and others on +the Tor network if you so desire. The Tor project provides a web service +to fetch a list of all IP addresses of Tor exit nodes that allow exiting to a +specified IP:port combination, and an official DNSRBL is also available to +determine if a given IP address is actually a Tor exit server. Please +be considerate +when using these options. It would be unfortunate to deny all Tor users access +to your site indefinitely simply because of a few bad apples.
