I opened up the prototype that I put together and had my first visitor who uploaded a great sequence of images showing how you would find a site: [edit: removed prototype, but it was just a modern, slimmed down version of the Mushroom Observer].
The other listing doesn't have an exact location, but has a purchase button labeled "Request Exact Location"... so I think the concept should now be a lot clearer.
A psychonaut from The Shroomery forum linked me to the Mushroom Observer: http://mushroomobserver.org/observer/observation_search?pattern=psilocybe+semilanceata
So the idea has a solid legal standing, at least for science...
I believe I am onto something extraordinary here.
And for all those afraid of the mythical neck-beard rapists; the dead drops don't necessarily have to be deep in the forest where mushrooms grow... could be in a plastic bag under a trash can in the park or street corner where no one would normally look.
The tradational DarkNetMarkets would still be vital - and grow deeper roots to support this new growth in the open. This can be set up on OpenBazaar with a few clicks for individual vendors or small networks, but what we really need is a version of OpenBazaar that supports multi-vendors linked to a map in the clearnet: https://imgur.com/Wrtu8c8.jpg
Leo doesn't throw a tantrum. They buy coordinates then pull security cam footage around the park or wherever. Leo nails vendor within a month.
