I gave warning on I0Guild. 24 hours of warning where you had full withdrawal capabilities, and even then the server stayed up for over 24 additional hours where I responded to withdrawal requests manually. It took that much extra time just to give payouts enough confirms to reach the exchange before the network imploded.
I think the point of some of the complaints were the so called "24 hour notice" was extremely weakly worded and did not sufficiently notify miners that they needed to withdrawl immeidatly or else they would forfiet thier coins.. In fact the warning implied the site was simply being moved (at an indeterminent time) and the pool would continue to run... It wasn't until after it the site was taken down where any mention/sugestion that the pool was being solely to support withdrawls to exchanges.
Either way, sounds like the wallets backing the pool have probabaly been destroyed... And as pointed out previously all those coins should simply be presumed lost forever. That is the nature of these projects, if anyone had any true value at stake, the code is open source and anyone could have fixed it sooner had they had the economic incentive to do so.
