Drug trade messages on Tor in Finnish, English and Polish

Within the Tor network, we compared the Finnish, English and Polish drug trade. To accomplish this, we selected three active onion websites. We compile and publish these three datasets, freely available to the academic community.1. A Finnish website within the Tor network offers an anonymous chat messenger and chat rooms for the biggest towns in Finland, where most of the messages are associated with the illicit drug trade. Finnish sample / Finnish.zip: 1,500 messages from the Finnish onion website “Tsatti”. We collected these in November and December of 2022. Anonymous chat Tsatti—Finnish discussions on Tor: http://tsattickdplsh2i2xqzlybvreiuppgoqsicmzkrotuudnk7h665ukgid.onion/2. The Polish forum website “Cebulka” operates anonymously within Tor and facilitates drug trafficking. Polish sample / Polish.zip: 965 advertisement pages from the “Cebulka” onion website in Polish.
