damn, the site was down and I've got scared by these scam accusations here  , so requested a withdrawn of all my funds from poloniex (the site is up now btw)

And it has been transferred w/o problems.  False alarm. 

Will send them back now, as they are needed for trading. I like the exchange btw, when it's up of course. But the Balances page can be improved, not very convenient atm.
