Facebook 提供了透過 Tor 連上 Facebook 的人數：「1 Million People use Facebook over Tor」：
In June 2015, over a typical 30 day period, about 525,000 people would access Facebook over Tor e.g.: by using Tor Browser to access www.facebook.com or the Facebook Onion site, or by using Orbot on Android. This number has grown – roughly linearly – and this month, for the first time, we saw this “30 day” figure exceed 1 million people.
去年六月的時候大約是 52 萬人，而現在則超過一百萬了。
