I got an email from Lysergi, one of the most popular (legal) RC vendors out. Talking about how they're closing, and adding a few specifics as to why they're closing.
While this doesn't directly apply to being a "DarkNetMarket" it certainly relates to it, and plenty of people here have probably used them before since it's an extremely popular RC vendor.
Here's the specific part in context:
"To address recent comments about customs seizures and missing product, it is true that there have been some strange things happening with Xpresspost packages sent to the US. US customs appear to be profiling all Xpresspost packs that are routed through JFK airport. And we are not the only vendors affected by this. Since this affects most of the US, we are now shipping ALL packages to the US via Snail Mail, regardless of the method selected at checkout. We will ship by Xpresspost again once the customs issues are resolved. We aim to change the shipping method options at checkout in the next few days to avoid confusion but this message (and several warnings on the website) should serve as notice. If you accidentally select Xpresspost USA at checkout we will ship via Snail Mail and include 2 x 100mcg 1P-LSD blotters to offset the costs. If you are forced to select Xpresspost USA due to your order value exceeding CAD250, we will still ship via Snail Mail. No postage refunds will be given for selecting Xpresspost USA. Domestic and international (non-US) orders are unaffected - please ignore the message.
An important note: please keep the 'exit scam' conspiracies to a minimum. It creates unnecessary FUD and increases our workload as customers bombard us with ridiculous questions."
This is extremely interesting. JFK is seizing enough of their Xpresspost packs from Canada (not even NL) for them to completely stop doing Xpresspost packs, and cause enough of a hassle for them to close their doors.
Keep in mind, even though what they're doing is technically legal, and the stealth is good (just any regular package, unmarked, and has a package inside of a package), they're still getting seized..
And JFK is an extremely popular customs stop for foreign packs.
Just something to think about.
