Silk Road scare mongering.
I hope you're not referring to me there.
I know Silk Road has a lot of support here, but it does not really require bitcoin - it could work with cash in the same manner and be even more secure.
Buying drugs through the mail is nothing new. I am unconvinced though that mailing cash payments is more secure than making payments with Bitcoin. Off topic though. Pretty sure we have other threads for that.
