Have you been able to withdraw from cryptsy in the past? Did you receive any kind of confirmation email, or an email asking you to confirm your withdrawal? Do you know if they usually send such emails prior to processing withdrawals?
yes, yes and yes. Exactly in that order. With more than one currency. And everything went fine in every case.
It looks like there is another thread making a large number of fairly serious claims against cryptsy, although I have not looked into the allegations contained in that thread, it would be possible they are experiencing some kind of financial difficulties.
I find it very strange they would all of a sudden stop allowing only certain people to withdraw from their account.
