>I tried 4chan/cbts/index.html and got a 404 yesterday
I'd expect that. Threads sunset there rather quickly. I think most everything from 4ch is in http:// archive.is/search/?q=%2Fcbts%2F
I got 22,900 hits. Some people used 4plebs and maybe even other archives. Need to know all of the archive sites used so we can add them to the soup.
A search on 4 plebs from 10-28-2017 to the night of the bans, 11-26-2017 shows 714 hits.
