Could be, but would they really dare to mock themselves in the honeypot? If it is a honeypot, it's very convincing and elaborate.
There is no other way to run a honeypot. Reminder that the feds ran the two largest carding forums on the web:
http://en.wikipedia.org/wiki/DarkMarket
They almost entirely destroyed English-language US-based carding forums in the process.
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
That said, I agree with other comments here as to why it's unlikely to be a honeypot.
Of course they would. The makers of a maximally-effective honeypot aren't going to shy away from making fun of TLAs. They'll do what's most effective.
With that said, I doubt it's a honeypot. Of course I don't plan to test that hypothesis.
