That's why I rarely use 4tan.
For /co/, the usual procedure is to search with desuarchive, and then get any full images I need using fireden or yuki.la
, since desuarchive's image server is dying.>>93651576
The filename from >>93650954
Neither of these links work though:https://i.4cdn.org/co/1499216190594.pnghttps://i.4cdn.org/ic/1499216190594.png
So it doesn't look like the image was posted there. However, that may be because either the file, post, or containing thread was deleted on 4chan.
The next approach is to search for the post numbers on /co/ and /ic/ made around that time in the archives.
For /co/, the timestamp 2017-07-05 12:56:30 AM (UTC) falls between posts >>93648516
. In particular, >>93648516
is an image post with timestamp 2017-07-05 12:56:29 AM (UTC), while the next image post is >>93648517
with UNIX timestamp 2017-07-05 12:56:31 AM (UTC). Which means whoever posted >>93650954
didn't copy it from a /co/ thread.
For /ic/, the timestamp 2017-07-05 12:56:30 AM (UTC) falls between posts >>>/ic/3048016
. Again, >>>/ic/3048015
is an image post with timestamp 2017-07-05 12:53:52 AM (UTC), while the next image post is >>>/ic/3048022
with timestamp 2017-07-05 01:00:20 AM (UTC). Which means whoever posted >>93650954
didn't copy it from an /ic/ thread either.
So wherever >>93650954
got it from, it wasn't /co/ or /ic/, but either some other board on 4chan, or some other chan that uses UNIX timestamps.
Moreover, the archive image hash for the image in >>93650954
is 7vAZbhuAOMdPVsGuqKTX1w (foolfuuka archivers use MD5 in Base64), but if you try searching that hash on all foolfuuka archives listed athttp://archive.4plebs.org/_/articles/credits/
you'll find no matches, except for this post >>93650954
. This might be because >>93650954
edited the pic though, so it's not conclusive. I'd need to write some archive scripts to go any further.
