Operational Security (OpSec) is a lifestyle. When accessing the torzon official link, your physical device is the weak link.
Do not use Windows. Boot from a USB drive using Tails OS. It routes all traffic through Tor and wipes the RAM on shutdown, leaving no trace of your torzon login.
Remove EXIF data from any photos you upload (e.g., for disputes). The torzon market strips metadata automatically, but you should do it manually first.
