Opsec issues?
Word of mouth?
Random LE searching networks and shit for some crazy sensitive computer info?
Packs ripping open?
I've read on here some people ordering packs steadily, 2-3/week for a year + and never having any hiccups
Also some people write they get caught in one of their first adventures into the dnm
Its your whore mouth. Honestly, for non-vendors, I'd imagine the biggest risk is when people talk about how they source their drugs.
Also, letting packs RTS is not a good thing. If you aren't ordering to a drop and you let a pack RTS, you are vulnerable. While probably not DNM related, I've read many news articles where a random citizen gets a package that's been RTS'ed, tehy open it and find drugs, call cops. Cops investigate.
I don't know how common this is but it's happened once really bad on an order of mine. I'm talking COMPLETELY ripped apart and contents strewn. Now, this vendor I used had fucking slick decoy and packaging that it was fine. But fuck, my heart stopped when I saw a USPS plastic bag with the contents and a completely torn box. But everything was there. Now, some vendors decoy would completely fail in this sort of scenario. But ripping open should not be common, but it does happen. A good vendor should have a pack that survives this scenario. But there are plenty of vendors who don't employ great decoys.
Considering how many orders are happening, the rate of getting pinched is pretty damn low. It could be just fucking bad luck - like if that pack I ordered was from another vendor I used to use who had absolutely no stealth, this would have been a big problem. I got lucky I used a different vendor on that order.
Also, misdeliveries. I've had my pack delivered to the wrong address a few times. This makes me nervous b/c sometimes people don't look closely at the label when they see a pack.
I've never had an issue though in all the years I've been ordering. I've always used well regarded vendors, I don't go straight to the cheapest vendor out there. Price obvioulsy plays a part but I don't pick a vendor just b/c they are the cheapest - I need to trust them.
Also, people doing stupid shit with their drops. Do not use a drop you do not control. People that do stupid shit - like putting a pack in previous tenant's name, using a vacant home - while they think they are being safer, they are actually exposing themselves much, much more. Be fucking safe. Its not complicated. People are idiots though and make something relatively safe more complicated b/c of irrational fears.
