Just as I thought. In that search all the examples of missing images are from archive.moe before 2015 (no relation to archived.moe).
Nothing got "worse": rather, we've just integrated archive.moe sql and thumbs for the first time.
Unfortunately, we have not yet integrated any archive.moe images since it will require another 20TB of hard drives to serve publicly. But we're thinking about it: barely got enough funding to maintain the drives we got now.
However, anyone can pick them up from the Internet Archive in the meantime. https://archive.org/details/@archivemoe
Now, even then some of those thumbs and images from 2015 and before are missing here and there. Unfortunately, what you see is what you get. Archive.moe failed to do the rsync correctly the one time it counted, before Foolz wiped everything.https://twitter.com/ArchiveMoe/status/512991440608043009
Although the thumbnail doesn't show up, if you click View Same
and it was reposted more recently, sometimes you can find the image from the hash.https://desuarchive.org/_/search/image/NSrq9MpCIuV5LByPVNJBrQ/
