The stock of these items is absolutely absurd considering how little time passed from the start of D2R. But there are still people for whom earning a couple of FGs by playing D2R 24/7 is the best way to make decent living, so maybe that's the case? I haven't seen bots (Xbox) yet, so I doubt it's that. Duping? Well, I think that if it was possible, I would already have bought several Enigmas while I'm still saving for the first one.
