My Deep Web illicit marketplace research uses transaction and marketplace lifespan data, public forum posts, user profiles, and private messages, to examine the identity and trust practices of vendors, customers, and site administrators and moderators. This began as a study of identity and trust practices on the marketplace known as Silk Road, and I initially found that trust and reputation could indeed be established in these illicit and high risk spaces despite the anonymity of participants. This led me to broaden my analysis to include market behavior, identity, and trust across a number of Deep Web marketplaces for illicit goods, with data going back to early 2012 and covering periods before during and after large site-wide busts and scams.
