I haven't looked into this, so I'll just give generic advice:

If it looks like a scam, it's more than likely a scam. Giving these fuckers the benefit of the doubt only puts people at risk. If they're innocent they should prove it with solid evidence.

Judging from your comment earlier, it looks very fishy indeed (once again, I'm basing my assumptions on your observation alone). If it's legit, my apologies, but so far everyone that came up with slightly shady stuff turned out to be guilty.
