go figure, it is not rocket science, someone has been selling non-existent coins and the swamp administered it. Good luck to anybody willing to deal with the swamp, you'll need it.
I never had much love for Bitstump after they told people "You remember those funds you sent us? We're going to need an identity theft kit from you if you want them back." IIRC, even Gox gave people fair warning. I was all done with exchanges before Bitstump came on-line so I was only watching from the sidelines.
no they didn't give fair warning. At least not in my case. Out of nowhere KYC stuff was required to pull my coins (early 2013). Thanks god I pulled out in disgust at that point.
