Public archives are dead.
I used to maintain a few pages dedicated to archiving the history of certain boards, but these days archive.ph just won't cooperate. I can't even use it to archive the index of a slow imageboard without it spitting a bullshit error at me.
I still feel really bad about not saving anything from geocities.jp beyond a screencap of a page or two, and a few flash files. To be fair, I actually trusted archiveteam would pull through and scrape everything, so I wasn't really worried at the time
Whenever anyone goes on a "copypaste some kanji before:2015 in the search bar and find weird images" rabbithole hootenanny, the first couple thousand results you're going to receive are hosted on fc2, so it's certainly going to be weird to see what sites will surface once it's gone.
