The fact that the scammer's are buying hardware in this forum's group pool indicates pretty clearly that an experienced member of the forum is involved in this scam.  Obviously into bitcoin mining themselves.

Any experienced forum members writing in defense of this scam?

Oh, I guess there are a few, eh?  The prime suspects are the guy who said he bought a bunch of them, and had the block chain entry to "prove it," and the Hawaii dude.  

Posts an order on his scam website, then pays with a different wallet, then posts to "prove" he really believes in this scam.  I'm not an expert in the block chain, so if this would not work for some reason, I'd be glad to hear an explanation as to why.

Of course, it could be someone who doesn't post much too.  But I'd love to see if someone could track down the pool member who is buying hardware with these bitcoins.  Seems like we could identify the criminal that way.  Wouldn't that be possible for the guy who runs the pool?

If we got the forum member's i.d., then we'd have an email address, and the feds might even be able to get his I.P. address.  And we're off to drag this/these scumbags to prison.
