  5. This notice is intended to be placed on a virtual host for a domain that
  6. your Tor exit node IP reverse resolves to so that people who may be about
  7. to file an abuse complaint would check it first before bothering you or
  8. your ISP. Ex:
  9. http://tor-exit.yourdomain.org or http://tor-readme.yourdomain.org.
  10. This type of setup has proven very effective at reducing abuse complaints
  11. for exit node operators.
  12. There are a few places in this document that you may want to customize.
  13. They are marked with FIXME.

  17. <center><h1>This is a Tor Exit Router</h1></center>
  18. <p>Most likely you are accessing this website because you had some issue with
  19. the traffic coming from this IP. This router is part of the <a
  20. href="https://www.torproject.org/">Tor Anonymity Network</a>, which is
  21. dedicated to <a href="https://www.torproject.org/30seconds.html.en">providing
  22. privacy</a> to people who need it most: average computer users. This
  23. router IP should be generating no other traffic, unless it has been
  24. compromised.
  25. <p>

  27. and serve it locally -->

  30. <p>
  31. Tor sees use by <a href="https://www.torproject.org/torusers.html.en">many
  32. important segments of the population</a>, including whistle blowers,
  33. journalists, Chinese dissidents skirting the Great Firewall and oppressive
  34. censorship, abuse victims, stalker targets, the US military, and law
  35. enforcement, just to name a few. While Tor is not designed for malicious
  36. computer users, it is true that they can use the network for malicious ends.
  37. In reality however, the actual amount of <a
  38. href="https://www.torproject.org/faq-abuse.html">abuse</a> is quite low. This
  39. is largely because criminals and hackers have significantly better access to
  40. privacy and anonymity than do the regular users whom they prey upon. Criminals
  41. can and do <a
  42. href="http://voices.washingtonpost.com/securityfix/2008/08/web_fraud_20_tools.html">build,
  43. sell, and trade</a> far larger and <a
  44. href="http://voices.washingtonpost.com/securityfix/2008/08/web_fraud_20_distributing_your.html">more
  45. powerful networks</a> than Tor on a daily basis. Thus, in the mind of this
  46. operator, the social need for easily accessible censorship-resistant private,
  47. anonymous communication trumps the risk of unskilled bad actors, who are
  48. almost always more easily uncovered by traditional police work than by
  49. extensive monitoring and surveillance anyway.
  50. <p>
  51. In terms of applicable law, the best way to understand Tor is to consider it a
  52. network of routers operating as common carriers, much like the Internet
  53. backbone. However, unlike the Internet backbone routers, Tor routers
  54. explicitly do not contain identifiable routing information about the source of
  55. a packet, and no single Tor node can determine both the origin and destination
  56. of a given transmission.
  57. <p>
  58. As such, there is little the operator of this router can do to help you track
  59. the connection further. This router maintains no logs of any of the Tor
  60. traffic, so there is little that can be done to trace either legitimate or
  61. illegitimate traffic (or to filter one from the other). Attempts to
  62. seize this router will accomplish nothing.
  63. <p>
  64. <!--- FIXME: US-Only section. Remove if you are a non-US operator -->
  65. Furthermore, this machine also serves as a carrier of email, which means that
  66. its contents are further protected under the ECPA. <a
  67. href="http://www4.law.cornell.edu/uscode/html/uscode18/usc_sec_18_00002707----000-.html">18
  68. USC 2707</a> explicitly allows for civil remedies ($1000/account
  69. <i><b><u>plus</u></b></i> legal fees)
  70. in the event of a seizure executed without good faith or probable cause (it
  71. should be clear at this point that traffic with an originating IP address of
  72. FIXME_DNS_NAME should not constitute probable cause to seize the
  73. machine). Similar considerations exist for 1st amendment content on this
  74. machine.
  75. <p>
  76. <!-- FIXME: May or may not be US-only. Some non-US tor nodes have in
  77. fact reported DMCA harassment... -->
  78. If you are a representative of a company who feels that this router is being
  79. used to violate the DMCA, please be aware that this machine does not host or
  80. contain any illegal content. Also be aware that network infrastructure
  81. maintainers are not liable for the type of content that passes over their
  82. equipment, in accordance with <a
  83. href="http://www4.law.cornell.edu/uscode/html/uscode17/usc_sec_17_00000512----000-.html">DMCA
  84. "safe harbor" provisions</a>. In other words, you will have just as much luck
  85. sending a takedown notice to the Internet backbone providers. Please consult
  86. <a href="https://www.torproject.org/eff/tor-dmca-response.html">EFF's prepared
  87. response</a> for more information on this matter.
  88. <p>For more information, please consult the following documentation:

  94. <p>
  95. That being said, if you still have a complaint about the router, you may
  96. email the <a href="mailto:FIXME_YOUR_EMAIL_ADDRESS">maintainer</a>. If
  97. complaints are related to a particular service that is being abused, I will
  98. consider removing that service from my exit policy, which would prevent my
  99. router from allowing that traffic to exit through it. I can only do this on an
  100. IP+destination port basis, however. Common P2P ports are
  101. already blocked.
  102. <p>You also have the option of blocking this IP address and others on
  103. the Tor network if you so desire. The Tor project provides a <a
  104. href="https://tor-svn.freehaven.net/svn/tor/trunk/contrib/exitlist">python script</a> to
  105. extract all IP addresses of Tor exit nodes, and an official <a
  106. href="https://www.torproject.org/tordnsel/">DNSRBL</a> is also available to
  107. determine if a given IP address is actually a Tor exit server. Please
  108. be considerate
  109. when using these options. It would be unfortunate to deny all Tor users access
  110. to your site indefinitely simply because of a few bad apples.
