The cautious approach
For readers who are worried about being watched. Each article picks one specific situation and walks through it slowly.
The three addresses
Nexus Market publishes these three onion addresses. Present as supplied, in no order, with no ranking. This site does not probe them and shows no uptime figure.
nexusb2l7fmqnefwphyy7m5zjhlkytlbo7qbb5lu5dlczr3azgii2gyd.onion
nexusma2iqgauqqvjcgds4ckv5xbf272tkfagq4epojjhsgleqpwxiqd.onion
nexusabcd6tyfhdwilyitaqiri6tisj2v2hueyjuj6qkvd6azvi5tuqd.onion
The cautious approach is not paranoia and it is not a security tutorial. It is a way of walking to the nexus market address that treats the network, the screen and the person in the next chair as things that might be paying attention.
Nothing in this group asks the reader to install extra tools or to pay for anything. It is about pacing, order, and where you stand while you look.
