    103103=== Tor over Tor ===
    104 When using a transparent proxy, it is possible to start a Tor session from the client as well as from the transparent proxy, creating a "Tor over Tor" scenario. Doing so produces undefined and potentially unsafe behavior. In theory, however, you can get six hops instead of three, but it is not guaranteed that you'll get three different hops - you could end up with the same hops, maybe in reverse or mixed order. It is not clear if this is safe. It has never been discussed.

    106106You can [https://www.torproject.org/docs/faq.html.en#ChooseEntryExit choose an entry/exit point], but '''you get the best security that Tor can provide when you leave the route selection to Tor; overriding the entry / exit nodes can mess up your anonymity in ways we don't understand.''' Therefore Tor over Tor usage is highly discouraged.
