After not receiving an answer to two support tickets about same issue over several days, I moved my steem off Poloniex to Bittrex via BTC. Just seen the bright yellow warning on Poloniex on the actual trade chart! It wasn't there 7 hours ago, yet Steem/ SBD has been disabled for a week or more. I guess many people are moving out due to previous lack of communication. 7 coins are still disabled.
Looking at various cases described by Polo users, you never know when they refuse your withdrawal.
They would need a lot of effort to rebuild their reputation. And they need to start that process now.
