Poloniex scammers, be careful!!! Poloniex does not give BTC for 14 days! Support is silent. Be careful with your coins!!! 
Is there any announcement for this or based on your experience or they told you in private by responding tickets?
The problem is I have no idea why my withdrawal is in status awaiting approval, waiting almost a month , I wrote two ticket without answer, so how can I told you why my transacton is blocked?
A month?? What's happening in poloniex, their have disabled the trollbox so there is no response from the moderators there, if they can't respond to the tickets then this is not a good thing, they start with delays and at the end they may end scamming which I'm very afraid.
