I have a sneaking suspicion that it's a honeypot. Just a hunch.
Could be, but would they really dare to mock themselves in the honeypot? If it is a honeypot, it's very convincing and elaborate.
What I don't really know, I guess, are the legal implications of entraping people on such a mass scale.
I'm also not sure about the usefulness of such a honeypot, since you can't actually track the buyers. Just because someone pays you to send drugs to some address, doesn't mean it's their own address
