在「Black-market archives」這篇給出了一份很寶貴的資料，是來自於 Tor hidden service 上的 Dark Net Markets (DNM)。
這份資料涵蓋了 2013 到 2015 年的各種紀錄：
From 2013-2015, I scraped/mirrored on a weekly or daily basis all existing English-language DNMs as part of my research into their usage, lifetimes/characteristics, & legal riskiness; these scrapes covered vendor pages, feedback, images, etc.
大約壓縮後 50GB 的資料：
This uniquely comprehensive collection is now publicly released as a 50GB (~1.6TB) collection covering 89 DNMs & 37+ related forums, representing <4,438 mirrors, and is available for any research.
Tor 的 hidden service 應該只會愈來愈流行，初期的這些資料會讓後人有很多題材可以分析...
