I was checking that out as well. Once the "seller" replied the pin was in Buffalo I knew for certain (as opposed to the 85% certainty before). Of course, a quick check of the Buffalo CL showed no AFM. Seriously, just stupid.
I'm gonna be pissed if I get there after a 5 hour drive and there is no machine!!!
This thread isn't a bad idea, though I suppose it is up to you to update the initial post through with any other confirmed scams to keep a quick "active" list.
