Abstract:

Background: Previous research on darknet drug markets has primarily concentrated on large, English-language cryptomarkets, often overlooking regionally oriented platforms that operate in national languages. This study adopts a comparative, exploratory approach to examine how drug trade practices vary across linguistic, geographic, and technological contexts. We introduce the concept of “drug trading ecologies” to describe how platform features, communication norms, and localized settings together shape distinct trading environments.

Methods: Using a mixed-methods approach, we analyzed web-crawled data from three Tor-based platforms: Tsatti (Finnish-language chat), Cebulka (Polish-language forum), and Nemesis (English-language cryptomarket). Data were collected through customized web scraping and analyzed using statistical tools and qualitative content coding to examine platform-specific patterns. Our comparative approach highlights structural and localization-specific variations without attempting exhaustive conceptual definitions.

Results: Each platform displayed a distinct configuration shaped by its technical affordances and localization-specific user practices. Tsatti supported fast, hyperlocal, and highly anonymized exchanges with minimal user identity or community features. Cebulka enabled semi-public vendor-buyer interactions, trust-building through discourse, and diverse product bundling. Nemesis functioned as a transnational, professionalized cryptomarket with standardized listings, formalized trust mechanisms, and branding strategies.

Conclusions: Rather than attributing differences solely to local, transnational, or design factors in isolation, we argue that darknet drug trading ecologies emerge from the intersection of platform architecture, localization (geographic scope), and language. Our findings underscore the importance of considering these factors when conducting digital ethnography in illicit economies and providing concrete entry points for tailoring harm reduction interventions responsive to the diverse realities of online drug trading.
