maybe that is the reason. but that would nit explain why LTC and several other coins are also t.a.
Anyways if you have any of these coins stuck on Poloniex you can use the same process that I described to @komischername. in EN:
- Transfer your STEEM on Polo to BTC
- Transfer BTC to Bittrex (Bitshares or any other exchange that has STEEM listed)
- Trade BTC for STEEM
- Transfer STEEM to your Steemit account
