Ask HN: CiteSeer purged their document caches?

Nearly every paper I have attempted to read this whole past week had no cached versions, so a good chunk of them had dead links and necessitated further googling, with money gone for good. I am not sure they're trying to discourage the use of free CiteSeer, since their commercial CiteSeerX doesn't even have those documents. If they deleted their document cache to save space or discourage use, they have committed a crime against research, imo. Could you please keep your eyes open over the next week, and whenever you happen to be chasing a paper, check to see if the cached-version link is there or not.
