When I was first poking around with Tor, I wondered how many of the "Get guns in Europe", "Hard Drugs here", "Credit Card Numbers for sale" and such links were honeypots. Luckily, not being interested in any of those things, I didn't have to find out.
Most of the legit stuff was on telegram, surprisingly or not. I know people who bought uh firearms and more there. Unfortunately, it feels like it disappeared at the same time as the proximity feature
If they use surveillance coins like BTC they are 100% a honeypot/scam.
