I've noticed something relevant to current discussion about Tor use.

Silk Road was taken down by the FBI on 2014-10-02.[0] The site still
loaded, however, showing a "This Hidden Site Has Been Seized" message.
And so it probably took a few days for most users to get the news.

Also, contemplating Figure 8, there may be a discontinuity at about July
2013, when they took down Freedom Hosting.[1]

I'm not aware of anything major in May-June of this year.
