It seems the same person deposited a pile of Qora to Poloniex on another account, dumped a lot of it, and withdrew around 14M. I have frozen this account as well. There is 0.80 BTC in this account. I believe I have closer to 24M Qora from the other account, but the block explorer keeps changing its mind about transactions, so I can't be certain.
Curiously, the account holder had plenty of opportunity to withdraw the 0.8 BTC, but never did. The only reason I have to believe that the accounts are connected is that this account also withdrew to the Sharexcoin address.
Has no one heard anything from Sharexcoin? Did they just vanish without a word?
As an
ex-supporter of ShareXcoin, I will try to summarize the situation. However I need to go to work soon so I will skip the details.
Few weeks ago, the website was down (error 500) for close to 24 hours. Zip (ziplibrary, the dev) stay silent all that time. We started to panic. When he came back, he explained it was a technical glitch, apologized for his silence and promised to add a monitoring system to the exchange so he will be aware of the problems if this happen again. OK, must of us forgave him and forgot about that.
About the current problem, on Twitter he posted something about glitch for deposit/withdraw of QORA. It was fixed he said. But then deposit/withdraw of all coin didn't work. Later the website went down. We assumed it was a DDoS. Once again Zip was silent. Trusting him we have been patient. But after more than 24 hours of silence, we started to panic again. His last active date on here is June 03, 2014, 12:46:41 PM.
When we heard about the big transfert of coin between ShareXcoin and Poloniex, must of us realized it was a scam.

Here my post that sumarize the latest event:
