By disabling trollbox they are censored customer complains about indefinite "Awaiting approval" withdrawals. Poloniex needs to be audited, they are lost customer's trust.
you meant it's about time to move deposited coin from Polo to safe wallet? I think if Polo is audited, auditor will find may problem while they don't welcome customers "When" request.
I may consider leaving little amount of coins there and store back to proper wallets.
Yes, if you can. Not joking. Simply try other exchanges like Bitfinex or Bittrex or Cryptopia or Gemini..
