“This is really going to impact institutions that we take for granted,” Internet Archive director of archiving and data services Jefferson Bailey told the Standard, “like our museums, our historical societies, our public libraries, our academic libraries — just a lot of people that keep information free and accessible and online.”
I made BBS posts in the early-mid 90s. They don’t exist anymore, because at that time the only BBSes I had any access to were local guys running one off a personal computer (and as such weren’t even available 24/7). The DMs and chats that happened there? If those guys actually kept the logs and kept transferring them from HD to HD, then I’ll be damned… but chances are likely they have disappeared into the ether.
