edit: Feeling kind of shitty for implying that an exit scam is for sure being pulled. I'd like to say that all of this together seems suspicious, but that these should be warning signs in the future if it turns out this is an exit scam. Otherwise, I'm just a shitty person tarnishing peoples reputations without anything but circumstantial proof.
edit 2: Definitely a scam, updated guide to reflect: https://www.reddit.com/r/DarkNetMarkets/comments/35x3lm/complaintwarning_received_controlled_delivery/
Not gonna mention the vendor likely pulling a huge exit scam right now, but here's an explanation of his methods so it may be avoided in the future.
Build up trust
Make shipping prices higher than need be
Offer free shipping for FE
Start off scam with 4/20 sale
When accused of being a scammer like previous 4/20 sales, remind them that full escrow is still available (though only through your expensive shipping option)
Up until 4/20 come through for your customers
Once 4/20 is over extend the sale and stop delivering on FE orders
Introduce artificial scarcity by saying the sale will end soon. This will entice people to order now, rather than waiting for public feedback. Customers also won't believe you're scamming because scammers don't usually mention limiting orders during a scam.
Every time your sale is about to end, find a reason to extend it further.
Eventually some of your FE customers will complain publicly that nothing has arrived. These customers will be taken care of by the skeptical in the community claiming FUD. Turn up in these threads and reassure everyone. Further complainers will be less likely to come forward since no one believed those that came before.
Offer tracking, though be reluctant to give it because "My dumb customers often ruin their plausible deniability by checking the tracking from their home address." (Also, consider sending a package to Bumfuck, Alaska giving those that still demand tracking the tracking for this package. Then say that you have no clue what could possibly be taking so long for the package to arrive.)
Continue in this state until public opinion finally sways out of your favor after weeks of public complaints.
Once you are figured out, go on reddit and claim you got CD'd so everyone things you got busted rather than that you are a dishonest dickhole. Even claim you are sending your CD post from behind bars, even though that makes no sense whatsoever.
It's actually really impressive how many people that have been tricked into FEing for the vendor.
Hahaha, subtle
