 [https://gitweb.torproject.org/tor.git/blob_plain/HEAD:/doc/spec/proposals/163
 -detecting-clients.txt Proposal 163] outlined some ways to detect clients,
 and [http://archives.seul.org/or/dev/Jun-2009/msg00018.html later emails]
 elaborated on the issue, clarifying some parts and exposing hopeless
 muddiness in others.

 There's an initial implementation of a variant of the concept in Tor now,
 under the RefuseUnknownExits configuration option.  Unfortunately, turning
 it on seems to give many positives.  We haven't investigated whether
 they're false positives or just jerks using Tor as a one-hop proxy.
