I used to browse the darknet for ****s and giggles. When I run into anything super shady like that I would write it down on a logsheet and make graphs of prices, quantities, and other neat factors like that. Last time I updated it was probably a few days before silk road went down. I never bought (or sold) anything, mostly because of my lack of faith in the actual anonymity of the bitcoin blockchain, and because I wasn't really interested. I'm almost certain a lot of the organs are from pigs.
I don't know about donating blood, I'm only 17, so I can't.
the darknet is spooky, kids. That's the end of this discussion.
also, gratz to noisyturtle.
