There are no victims here. Bitstamp is a regulated and legitimate exchange. Blocked funds (or perceived/assumed "losses") are most probably undergoing scrutiny or enhanced checks. I suggest you regularly contact them to remind them of any open and unresolved tickets. The one thing you should all remember is that exchanges are now very busy dealing with floods of new account registrations.

Remind them regularly of any unresolved issues and they will eventually resolve it. Bitstamp has been around for nearly a decade and they are one of the very few exchanges licensed to operate legally. They have an almost bank-like status in the EU.
